Device Description  
The TLE9263-3BQXV33 is a monolithic integrated circuit in an exposed pad VQFN-48 (7 mm x 7 mm) power  
package with Lead Tip Inspection (LTI) feature to support Automatic Optical Inspection (AOI).  
The device is designed for various CAN-LIN automotive applications as main supply for the microcontroller  
and as interface for a LIN and CAN bus network including the CAN Partial Networking feature.  
To support these applications, the System Basis Chip (SBC) provides the main functions, such as a 3.3 V low-  
dropout voltage regulator (LDO) for e.g. a microcontroller supply, another 5 V low-dropout voltage regulator  
with off-board protection for e.g. sensor supply, another 3.3 V/1.8 V regulator to drive an external PNP  
transistor, which can be used as an independent supply for off-board usage or in load sharing configuration  
with the main regulator VCC1, a HS-CAN transceiver supporting CAN FD and CAN Partial Networking (incl. FD  
tolerant mode) and LIN transceiver for data transmission, high-side switches with embedded protective  
functions and a 16-bit Serial Peripheral Interface (SPI) to control and monitor the device. Also implemented  
are a configurable timeout / window watchdog circuit with a reset feature, three Fail Outputs and an  
undervoltage reset feature.  
The device offers low-power modes in order to minimize current consumption on applications that are  
connected permanently to the battery. A wake-up from the low-power mode is possible via a message on the  
buses, via the bi-level sensitive monitoring/wake-up inputs as well as via cyclic wake.  
The device is designed to withstand the severe conditions of automotive applications.

Hints for Unused Pins  
It must be ensured that the correct configurations are also selected, i.e. in case functions are not used that  
they are disabled via SPI:  
WK1/2/3: connect to GND and disable WK inputs via SPI  
HSx: leave open  
LINx, RXDLINx, TXDLINx, CANH/L, RXDCAN, TXDCAN: leave all pins open  
RO / FOx: leave open  
INT: leave open  
TEST: connect to GND during power-up to activate SBC Development Mode;  
connect to VS or leave open for normal user mode operation  
VCC2: leave open and keep disabled  
VCC3: See Chapter 8.5  
VCAN: connect to VCC1  
n.c.: not connected; internally not bonded; connect to GND  
If unused pins are routed to an external connector which leaves the ECU, then these pins should have  
provision for a zero ohm jumper (depopulated if unused) or ESD protection.  
3.4  
Hints for Alternate Pin Functions  
In case of alternate pin functions, selectable via SPI, it must be ensured that the correct configurations are also  
selected via SPI, in case it is not done automatically. Please consult the respective chapter. In addition,  
following topics shall be considered:  
WK1..2: The pins can be either used as HV wake / voltage monitoring inputs or for a voltage measurement  
function (via bit WK_MEAS). In the second case, the WK1..2 pins shall not be used / assigned for any wake  
detection nor cyclic sense functionality, i.e. WK1 and WK2 must be disabled in the register WK_CTRL_2 and  
the level information is to be ignored in the register WK_LVL_STAT.  
FO2..3: The pins can also be configured as GPIOs in the GPIO_CTRL register. In this case, the pins shall not  
be used for any fail output functionality. The default function after Power on Reset (POR) is FOx.

Note:  
Within the functional range the IC operates as described in the circuit description. The electrical  
characteristics are specified within the conditions given in the related electrical characteristics  
table.  
Device Behavior Outside of Specified Functional Range:  
28V < VS,func < 40V: Device will still be functional including the state machine; the specified electrical  
characteristics might not be ensured anymore. The regulators VCC1/2/3 are working properly, however, a  
thermal shutdown might occur due to high power dissipation. HSx switches might be turned OFF  
depending on VSHS_OV configurations. The specified SPI communication speed is ensured; the absolute  
maximum ratings are not violated, however the device is not intended for continuous operation of VS >28V.  
The device operation at high junction temperatures for long periods might reduce the operating life time;  
18V < VS,LIN <28V: The LIN transceiver is still functional. However, the communication might fail due to out-  
of-LIN-spec operation;  
V
SHS,UVD < VS,LIN < 6V: The LIN transceiver is still functional. However, the communication might fail due to  
out-of-LIN-spec operation;  
VCAN < 4.75V: The undervoltage bit VCAN_UV will be set in the SPI register BUS_STAT_1 and the transmitter  
will be disabled as long as the UV condition is present;  
5.25V < VCAN < 5.50V: CAN transceiver still functional. However, the communication might fail due to out-of-  
spec operation;  
V
POR,f < VS < 5.5V: Device will still be functional; the specified electrical characteristics might not be ensured  
anymore.  
The voltage regulators will enter the low-drop operation mode  
(applies for VCC3 only if bit VCC3_VS_ UV_OFF is set),  
A VCC1_UV reset could be triggered depending on the Vrtx settings,  
The LIN transmitter will be disabled if VSHS,UVD is reached,  
HSx switch behavior will depend on the respective configuration:  
- HS_UV_SD_EN = ‘0’ (default): HSx will be turned OFF for VSHS < VSHS_UV and will stay OFF;  
- HS_UV_SD_EN = ‘1’: HSx stays on as long as possible. An unwanted overcurrent shut down may occur.  
OC shut down bit set and the respective HSx switch will stay OFF;

10) Also applies to Cyclic Wake  
Note:  
There is no additional current consumption contribution due to PWM generators.

System Features  
This chapter describes the system features and behavior of the TLE9263-3BQXV33:  
State machine  
SBC mode control  
Device configuration  
State of supply and peripherals  
System functions such as cyclic sense or cyclic wake  
Supervision and diagnosis functions  
The System Basis Chip (SBC) offers six operating modes:  
SBC Init Mode: Power-up of the device and after a soft reset,  
SBC Normal Mode: The main operating mode of the device,  
SBC Stop Mode: The first-level power saving mode with the main voltage regulator VCC1 enabled,  
SBC Sleep Mode: The second-level power saving mode with VCC1 disabled,  
SBC Restart Mode: An intermediate mode after a wake event from SBC Sleep or Fail-Safe Mode or after a  
failure (e.g. WD failure, VCC1 undervoltage reset) to bring the microcontroller into a defined state via a  
reset. Once the failure condition is not present anymore the device will automatically change to SBC  
Normal Mode after a delay time (tRD1).  
SBC Fail-Safe Mode: A safe-state mode after critical failures (e.g. WD failure, VCC1 undervoltage reset) to  
bring the system into a safe state and to ensure a proper restart of the system. VCC1 is disabled. It is a  
permanent state until either a wake event (via CAN, LINx or WKx) occurs or the overtemperature condition  
is not present anymore.  
A special mode, called SBC Development Mode, is available during software development or debugging of the  
system. All above mentioned operating modes can be accessed in this mode. However, the watchdog counter  
is stopped and does not need to be triggered. This mode can be accessed by setting the TEST pin to GND  
during SBC Init Mode.  
The device can be configured via hardware (external component) to determine the device behavior after a  
watchdog trigger failure. See Chapter 5.1.1 for further information.  
The System Basis Chip is controlled via a 16-bit SPI interface. A detailed description can be found in  
Chapter 16.The configuration as well as the diagnosis is handled via the SPI. The SPI mapping of the TLE9263-  
3BQXV33 is compatible to other devices of the TLE926x and TLE927x families.

System Features  
5.1.1  
Device Configuration and SBC Init Mode  
The SBC starts up in SBC Init Mode after crossing the power-on reset VPOR,r threshold (see also Chapter 15.3)  
and the watchdog will start with a long open window (tLW).  
During this power-on phase following configurations are stored in the device:  
The device behavior regarding a watchdog trigger failure and a VCC1 overvoltage condition is determined  
by the external circuitry on the INT pin (see below)  
The selection of the normal device operation or the SBC Development Mode (watchdog disabled for  
debugging purposes) will be set depending on the voltage level of the FO3/TEST pin (see also  
Chapter 5.1.7).  
5.1.1.1 Device Configuration  
The configuration selection is intended to select the SBC behavior regarding a watchdog trigger failure.  
Depending on the requirements of the application, the VCC1 output shall be switched OFF and the device shall  
go to SBC Fail-Safe Mode in case of a watchdog failure (1 or 2 fails). To set this configuration (Config 2/4), the  
INT pin does not need an external pull-up resistor. In case VCC1 should not be switched OFF (Config 1/3), the  
INT pin needs to have an external pull-up resistor connected to VCC1 (see application diagram in  
Chapter 17.1).  
Figure 5 shows the timing diagram of the hardware configuration selection. The hardware configuration is  
defined during SBC Init Mode. The INT pin is internally pulled LOW with a weak pull-down resistor during the  
reset delay time tRD1, i.e.after VCC1 crosses the reset threshold VRT1 and before the RO pin goes HIGH. The INT  
pin is monitored during this time (with a continuos filter time of tCFG_F) and the configuration (depending on  
the voltage level at INT) is stored at the rising edge of RO.  
Note:  
If the POR bit is not cleared then the internal pull-down resistor will be reactivated every time RO is  
pulled LOW the configuration will be updated at the rising edge of RO. Therefore it is recommended  
to clear the POR bit right after initialization. In case there is no stable signal at INT, then the default  
value ‘0’ will taken as the config select value = SBC Fail-Safe Mode.

Hardware Configuration Selection Timing Diagram  
There are four different device configurations (Table 5) available defining the watchdog failure and the VCC1  
overvoltage behavior. The configurations can be selected via the external connection on the INT pin and the  
SPI bit CFG in the HW_CTRL register (see also Chapter 16.4):  
CFGP = ‘1’: Config 1 and Config 3:  
A watchdog trigger failure leads to SBC Restart Mode and depending on CFG the Fail Outputs (FOx) are  
activated after the 1st (Config 1) or 2nd (Config 3) watchdog trigger failure;  
A VCC1 overvoltage detection will lead to SBC Restart Mode if VCC1_OV_RST is set.  
VCC1_ OV will be set and the Fail Outputs are activated;  
CFGP = ‘0’: Config 2 and Config 4:  
A watchdog trigger failure leads to SBC Fail-Safe Mode and depending on CFG the Fail Outputs (FOx)  
are activated after the 1st (Config 2) or 2nd (Config 4) watchdog trigger failure. The first watchdog  
trigger failure in Config 4 will lead to SBC Restart Mode;  
A VCC1 overvoltage detection will lead to SBC Fail-Safe Mode if VCC1_OV_RST is set.  
VCC1_ OV will be set and the Fail Outputs are activated;  
The respective device configuration can be identified by reading the SPI bit CFG in the HW_CTRL register and  
the CFGP bit in the WK_LVL_STAT register.

System Features  
5.1.1.2 SBC Init Mode  
In SBC Init Mode, the device waits for the microcontroller to finish its startup and initialization sequence. In  
the SBC Init Mode any valid SPI command will bring the SBC to SBC Normal Mode. During the long open  
window the watchdog has to be triggered. Thereby the watchdog will be automatically configured.  
A missing watchdog trigger during the long open window will cause a watchdog failure and the device will  
enter SBC Restart Mode.  
Wake events are ignored during SBC Init Mode and will therefore be lost.  
Notes  
1. Any SPI command will bring the SBC to SBC Normal Mode even if it is a illegal SPI command (see  
Chapter 16.2).  
2. For a safe start-up, it is recommended to use the first SPI command to trigger and to configure the watchdog  
(see Chapter 15.2).  
3. At power up no VCC1_UV will be issued nor will FOx be triggered as long as VCC1 is below the VRT,x threshold  
and if VS is below the VCC1 short circuit detection threshold VS,UV. The RO pin will be kept low as long as VCC1  
is below the selected VRT,x threshold.

System Features  
5.1.2  
SBC Normal Mode  
The SBC Normal Mode is the standard operating mode for the SBC. All configurations have to be done in SBC  
Normal Mode before entering a low-power mode (see also Chapter 5.1.6 for the device configuration defining  
the Fail-Safe Mode behavior). A wake-up event on CAN, LINx and WKx will create an interrupt on pin INT -  
however, no change of the SBC mode will occur. The configuration options are listed below:  
VCC1 is active  
VCC2 can be switched ON or OFF (default = OFF)  
VCC3 is configurable (OFF coming from SBC Init Mode; as previously programmed coming from SBC Restart  
Mode)  
CAN is configurable (OFF coming from SBC Init Mode; OFF or wake capable coming from SBC Restart Mode,  
see also Chapter 5.1.5)  
LIN is configurable (OFF coming from SBC Init Mode; OFF or wake capable coming from SBC Restart Mode,  
see also Chapter 5.1.5)  
HS Outputs can be switched ON or OFF (default = OFF) or can be controlled by PWM; HS Outputs are OFF  
coming from SBC Restart Mode  
Wake pins show the input level and can be selected to be wake capable (interrupt)  
Cyclic sense can be configured with HS1...4 and Timer1 or Timer 2  
Cyclic wake can be configured with Timer1 or Timer2  
Watchdog is configurable  
All FOx outputs are OFF by default. Coming from SBC Restart Mode FOx can be active (due to a failure event,  
e.g. watchdog trigger failure, VCC1 short circuit, etc.) or inactive (no failure occurred)  
In SBC Normal Mode, there is the possibility of testing the FO outputs, i.e. to verify if setting the FO pin to low  
will create the intended behavior within the system. The FO output can be enabled and then disabled again  
by the microcontroller by setting the FO_ON SPI bit. This feature is only intended for testing purposes.

SBC Stop Mode  
The SBC Stop Mode is the first level technique to reduce the overall current consumption by setting the  
voltage regulators VCC1, VCC2 and VCC3 into a low-power mode. In this mode VCC1 is still active and supplying  
the microcontroller, which can enter a power down mode. The VCC2 supply, CAN & LIN mode as well as the  
HSx outputs can be configured to stay enabled. All kind of settings have to be done before entering SBC Stop  
Mode. In SBC Stop Mode any kind of SPI WRITE commands are ignored and the SPI_FAIL bit is set, except for  
changing to SBC Normal Mode, triggering a SBC Soft Reset, refreshing the watchdog as well as for reading and  
clearing the SPI status registers. A wake-up event on CAN, LINx and WKx will create an interrupt on pin INT -  
however, no change of the SBC mode will occur. The configuration options are listed below:  
VCC1 is ON  
VCC2 is fixed as configured in SBC Normal Mode  
VCC3 is fixed as configured in SBC Normal Mode  
CAN mode is fixed as configured in SBC Normal Mode  
LIN mode is fixed as configured in SBC Normal Mode  
WK pins are fixed as configured in SBC Normal Mode  
HS Outputs are fixed as configured in SBC Normal Mode  
Cyclic sense is fixed as configured in SBC Normal Mode  
Cyclic wake is fixed as configured in SBC Normal Mode  
Watchdog is fixed as configured in SBC Normal Mode  
SBC Soft Reset can be triggered  
FOx outputs are fixed, i.e. the state from SBC Normal Mode is maintained  
An interrupt is triggered on the pin INT when SBC Stop Mode is entered and not all wake source signalization  
flags from WK_STAT_1 and WK_STAT_2 were cleared.  
Notes  
1. If switches are enabled during SBC Stop Mode, e.g. HSx on with or without PWM, then the SBC current  
consumption will increase (see Chapter 4.4).  
2. It is not possible to switch directly from SBC Stop Mode to SBC Sleep Mode. Doing so will also set the SPI_FAIL  
flag and will bring the SBC into Restart Mode.  
3. When WK1 and WK2 are configured for the alternate measurement function (WK_MEAS = 1) then the wake  
inputs cannot be selected as wake input sources.

SBC Sleep Mode  
The SBC Sleep Mode is the second level technique to reduce the overall current consumption to a minimum  
needed to react on wake-up events or for the SBC to perform autonomous actions (e.g. cyclic sense). In this  
mode, VCC1 is OFF and not supplying the microcontroller anymore.The VCC2 supply as well as the HSx outputs  
can be configured to stay enabled. The settings have to be done before entering SBC Sleep Mode. A wake-up  
event on CAN, LINx or WKx will bring the device via SBC Restart Mode into SBC Normal Mode again and signal  
the wake source. The configuration options are listed below:  
VCC1 is OFF  
VCC2 is fixed as configured in SBC Normal Mode  
VCC3 is fixed or OFF as configured in SBC Normal Mode  
CAN mode changes automatically from ON or Receive Only Mode to wake capable mode or can be selected  
to be OFF  
CAN must be set to CAN wake capable / CAN off mode before entering SBC Sleep Mode  
LIN mode changes automatically from ON or Receive Only Mode to wake capable mode or can be selected  
to be OFF  
WK pins are fixed as configured in SBC Normal Mode  
HS Outputs are fixed as configured in SBC Normal Mode  
Cyclic sense is fixed as configured in SBC Normal Mode  
Cyclic wake is not available  
Watchdog is OFF  
FOx outputs are fixed, i.e. the state from SBC Normal Mode is maintained  
As VCC1 is OFF during SBC Sleep Mode, no SPI communication is possible;  
The Sleep Mode entry is signalled in the SPI register DEV_STAT with the bit DEV_STAT  
It is not possible to switch all wake sources off in SBC Sleep Mode. Doing so will set the SPI_FAIL flag and will  
bring the SBC into SBC Restart Mode.  
In order to enter SBC Sleep Mode successfully, all wake source signalization flags from WK_STAT_1 and  
WK_STAT_2 need to be cleared. A failure to do so will result in an immediate wake-up from SBC Sleep Mode  
by going via SBC Restart to Normal Mode.  
All settings must be done before entering SBC Sleep Mode.  
Notes  
1. If switches are enabled during SBC Sleep mode, e.g. HSx on with or without PWM, then the SBC current  
consumption will increase (see Chapter 4.4).  
2. Cyclic Sense function will not work properly anymore in case of an overcurrent, overtemperature, under- or  
overvoltage (in case function is selected) event because the respective HS switch will be disabled.  
3. When WK1 and WK2 are configured for the alternate measurement function (WK_MEAS = 1) then the wake  
inputs cannot be selected as wake input sources.

5.1.5  
SBC Restart Mode  
There are multiple reasons to enter the SBC Restart Mode. The purpose of the SBC Restart Mode is to reset the  
microcontroller:  
in case of undervoltage on VCC1 in SBC Normal and in SBC Stop Mode,  
in case of overvoltage on VCC1 if the bit VCC1_OV_RST is set and if CFGP = ‘1’,  
due to 1st incorrect Watchdog triggering (only if Config1, Config3 or Config 4 is selected, otherwise SBC  
Fail-Safe Mode is immediately entered),  
In case of a wake event from SBC Sleep or SBC Fail-Safe Mode or a release of overtemperature shutdown  
(TSD2) out of SBC Fail-Safe Mode this transition is used to ramp up VCC1 after a wake in a defined way.  
From SBC Restart Mode, the SBC goes automatically to SBC Normal Mode, i.e the mode is left automatically  
by the SBC without any microcontroller influence. The SBC MODE bits are cleared. As shown in Figure 52 the  
Reset Output (RO) is pulled low when entering Restart Mode and is released at the transition to Normal Mode  
after the reset delay time (tRD1). The watchdog timer will start with a long open window starting from the  
moment of the rising edge of RO and the watchdog period setting in the register WD_CTRL will be changed to  
the respective default value ‘100’.  
Leaving the SBC Restart Mode will not result in changing / deactivating the Fail outputs.  
The behavior of the blocks is listed below:  
All FOx outputs are activated in case of a 1st watchdog trigger failure (if Config1 or Config2 is selected) or  
in case of VCC1 overvoltage detection (if VCC1_OV_RST is set)  
VCC1 is ON or ramping up  
VCC2 will be disabled if it was activated before  
VCC3 is fixed or ramping as configured in SBC Normal Mode  
CAN is “woken” due to a wake event or OFF depending on previous SBC and transceiver mode (see also  
Chapter 10). It is wake capable when it was in CAN Normal-, Receive Only or wake capable mode before  
SBC Restart Mode  
LIN is “woken” or OFF depending on previous SBC and transceiver mode (see also Chapter 11). It is wake  
capable when it was in LIN Normal-, Receive Only or wake capable mode before SBC Restart Mode.  
HS Outputs will be disabled if they were activated before  
RO is pulled low during SBC Restart Mode  
SPI communication is ignored by the SBC, i.e. it is not interpreted  
The Restart Mode entry is signalled in the SPI register DEV_STAT with the bits DEV_STAT

Notes  
1. An overvoltage event on VCC1 will only lead to SBC Restart Mode if the bit VCC1_OV_RST is set and if CFGP =  
‘1’ (Config 1/3).  
2. The content of the WD_FAIL bits will depend on the device configuration, e.g. 1 or 2 watchdog failures.  
5.1.6  
SBC Fail-Safe Mode  
The purpose of this mode is to bring the system in a safe status after a failure condition by turning off the VCC1  
supply and powering off the microcontroller. After a wake event the system is then able to restart again.  
The Fail-Safe Mode is automatically reached for following events:  
after an SBC thermal shutdown (TSD2) (see also Chapter 15.9.3),  
in case of overvoltage on VCC1 if the bit VCC1_OV_RST is set and if CFGP = ‘0’,  
after a 1st incorrect watchdog trigger in Config2 (CFG = 1) and after a 2nd incorrect watchdog trigger in  
Config4 (CFG = 0) (see also Chapter 5.1.1),  
if VCC1 is shorted to GND (see also Chapter 15.7),  
After 4 consecutive VCC1 undervoltage events (only if VS > VS,UV, see Chapter 15.6).  
In this case, the default wake sources (CAN, LINx, WK1...3, see also registers WK_CTRL_2, BUS_CTRL_1 and  
BUS_CTRL_2) are activated, the wake events are cleared in the register WK_STAT_1, and all output drivers  
and all voltage regulators are switched off. When WK1 and WK2 are configured for the alternate measurement  
function (WK_MEAS = 1) then WK1 and WK2 will stay configured for the measurement function when SBC Fail-  
Safe Mode is entered, i.e. they will not be activated as wake sources.  
The SBC Fail-Safe Mode will be maintained until a wake event on the default wake sources occurs. To avoid  
any fast toggling behavior a filter time of typ. 100ms (tFS,min) is implemented. Wake events during this time will  
be stored and will automatically lead to entering SBC Restart Mode after the filter time.  
In case of an VCC1 overtemperature shutdown (TSD2) the SBC Restart Mode will be reached automatically  
after a filter time of typ. 1s (tTSD2) without the need of a wake event.  
Leaving the SBC Fail-Safe Mode will not result in deactivation of the Fail Output pins.  
The following functions are influenced during SBC Fail-Safe Mode:  
All FOx outputs are activated (see also Chapter 14)  
VCC1 is OFF  
VCC2 is OFF  
VCC3 is OFF  
CAN is wake capable  
LINx is wake capable  
HS Outputs are OFF  
WK pins are wake capable through static sense (with default 16µs filter time)  
Cyclic sense and Cyclic wake is disabled  
SPI communication is disabled because VCC1 is OFF

5.1.7  
SBC Development Mode  
The SBC Development Mode is used during the development phase of the module. It is especially useful for  
software development.  
Compared to the default SBC user mode operation, this mode is a super set of the state machine. The device  
will start also in SBC Init Mode and it is possible to use all the SBC Modes and functions with following  
differences:  
Watchdog is stopped and does not need to be triggered. Therefore no reset is triggered due to watchdog  
failure  
SBC Fail-Safe and SBC Restart Mode are not reached due to watchdog failure but the other reasons to enter  
these modes are still valid  
LINx, CAN and VCC2 default value in SBC INIT MODE and entering SBC Normal Mode from SBC Init Mode is  
ON instead of OFF  
The SBC Development Mode is reached automatically if the FO3/TEST pin is set and kept LOW during SBC Init  
Mode. The voltage level monitoring is started as soon as VS > VPOR,f. The Development Mode is configured and  
maintained if SBC Init Mode is left by sending any SPI command while FO3/TEST is LOW. In case the FO3/TEST  
level will be HIGH for longer than tTEST during the monitoring period then the SBC Development Mode is not  
reached .  
The SBC will remain in this mode for all conditions and can only be left by powering down the device  
(VS < VPOR,f).

Note:  
The absolute maximum ratings of the pin FO3/TEST must be observed. To increase the robustness of  
this pin during debugging or programming a series resistor between FO3/TEST and the connector  
can be added (see Figure 66).  
5.2  
Wake Features  
Following wake sources are implemented in the device:  
Static Sense: WK inputs are permanently active (see Chapter 12)  
Cyclic Sense: WK inputs only active during on-time of cyclic sense period (see below)  
Cyclic Wake: internal wake source controlled via internal timer (see below)  
CAN wake: Wake-up via CAN message (see Chapter 10)  
LIN wake: Wake-up via LIN message (see Chapter 11)  
5.2.1  
Cyclic Sense  
The cyclic sense feature is intended to reduce the quiescent current of the device and the application.  
In the cyclic sense configuration, one or more high-side drivers are switched on periodically controlled by  
TIMER1_CTRL and TIMER2_CTRL. The respective high-side drivers supply external circuitries e.g. switches  
and/or resistor arrays, which are connected to one or more wake inputs (see Figure 5). Any edge change of the  
WKx input signal during the on-time of the cyclic sense period causes a wake. Depending on the SBC mode,  
either the INT is pulled low (SBC Normal Mode and Stop Mode) or the SBC is woken enabling the VCC1 (after  
SBC Sleep and SBC Fail-Safe Mode).

5.2.1.1 Configuration and Operation of Cyclic Sense  
The correct sequence to configure the cyclic sense is shown in Figure 6. All the configurations have to be  
performed before the on-time is set in the TIMERx_CTRL registers. The settings “OFF / LOW” and “OFF / HIGH”  
define the voltage level of the respective HS driver before the start of the cyclic sense. The intention of this  
selection is to avoid an unintentional wake due to a voltage level change at the start of the cyclic sense.  
Cyclic Sense (=TimerX) will start as soon as the respective on-time has been selected independently from the  
assignment of the HS and filter configuration. The selection of the respective timer (Config C/D see  
Chapter 12.2.1) must therefore be done before starting the timer. The correct configuration sequence is as  
follows:  
Configure the initial level  
Mapping of a Timer to the respective HSx outputs

Configuring the timer period and on-time

OPTIREG™ SBC TLE9263-3BQXV33  
System Features  
The first sample of the WK input value (HIGH or LOW) is taken as the reference for the next cycle. A change of  
the WK input value between the first and second cycle recognized during the on-time of the second cycle will  
cause a wake from SBC Sleep Mode or an interrupt during SBC Normal or SBC Stop Mode.  
A filter time of 16µs is implemented to avoid a parasitic wake-up due to transients or EMC disturbances. The  
filter time tFWK1 is triggered right at the end of the selected on-time and a wake signal is recognized if:  
the input level will not cross the switching threshold level of typ. 3V during the selected filter time (i.e. if the  
signal will keep the HIGH or LOW level) and  
there was an input level change between the current and previous cycle  
A wake event due to cyclic sense will set the respective bit WK1_WU, WK2_WU, or WK3_WU.  
During Cyclic Sense, WK_LVL_STAT is updated only with the sampled voltage levels of the WKx pins in SBC  
Normal or SBC Stop Mode.  
The functionality of the sampling and different scenarios are depicted in Figure 7 to Figure 9. The behavior in  
SBC Stop and SBC Sleep Mode is identical except that in Stop Mode INT will be triggered to signal a change of  
WK input levels and in SBC Sleep Mode, VCC1 will power-up instead.

in case SBC Fail-Safe Mode is entered: The respective HS Switch will be disabled and the respective wake

In SBC Normal, Stop, or Sleep Mode in case of an overcurrent, overtemperature, under- or overvoltage (in  
case function is selected) event: the respective HS switch will be disabled  
Note:  
The internal timers for cyclic sense are not disabled automatically in case the HS switch is turned off  
due to above mentioned failures.This must be considered to avoid loss of wake events.  
5.2.1.2 Cyclic Sense in Low Power Mode  
If cyclic sense is intended for SBC Stop or SBC Sleep Mode mode, it is necessary to activate the cyclic sense in  
SBC Normal Mode before going to the low power mode. A wake event due to cyclic sense will set the respective  
bit WK1_WU, WK2_WU or WK3_WU. In Stop Mode the wake event will trigger an interrupt, in Sleep Mode the  
wake event will send the device via Restart Mode to Normal Mode. Before returning to SBC Sleep Mode, the  
wake status register WK_STAT_1 and WK_STAT_2 needs to be cleared. Trying to go to SBC Sleep mode with  
uncleared wake flags, such as WKx_WU the SBC will directly wake-up from Sleep Mode by going via Restart  
Mode to Normal Mode, a reset is issued. The WKx_WU bit is seen as source for the wake. This is implemented  
in order not to loose an wake event during the transition.  
5.2.2  
Cyclic Wake  
The cyclic wake feature is intended to reduce the quiescent current of the device and application.  
For the cyclic wake feature one or both timers are configured as internal wake-up source and will periodically  
trigger an interrupt in SBC Normal and SBC Stop Mode.  
The correct sequence to configure the cyclic wake is shown in Figure 10. The sequence is as follows:  
First, disable the timers to ensure that there is not unintentional interrupt when activating cyclic wake,  
Enable Timer1 and/or Timer2 as a wake-up source in the register WK_CTRL_1,  
Configure the respective period Timer1 and/or Timer2. Also an on-time (any value) must be selected to  
start the cyclic wake even if the value is ignored.

5.2.3  
Internal Timer  
The integrated Timer1 and Timer2 are typically used to wake up the microcontroller periodically (cyclic wake)  
or to perform cyclic sense on the wake inputs. Therefore, the timers can be mapped to the dedicated HS  
switches by SPI (via HS_CTRL1...2).  
Following periods and on-times can be selected via the register TIMER1_CTRL and TIMER2_CTRL  
respectively:  
Period: 10ms / 20ms / 50ms / 100ms / 200ms / 1s / 2s

5.4.2.3 Wake-up Frame (WUF)  
The wake-up frame is detection is implemented as defined in ISO 11898-2:2016.  
Only CAN frames according ISO11989-1 are considered as potential wake-up frames.  
A bus wake-up shall be performed, if selective wake-up function is enabled and a "valid WUF" has been  
received. The transceiver may ignore up to four consecutive CAN data frames that start after switching on the  
bias.  
A received frame is a “valid WUF” in case all of the following conditions are met:  
The ID of the received frame is exactly matching a configured ID in the relevant bit positions. The relevant  
bit positions are given by an ID mask. The ID and the ID mask might have either 11 bits or 29 bits.  
The DLC of the received frame is exactly matching the configured DLC.  
Datasheet

Rev. 1.2  
2022-05-04  
OPTIREG™ SBC TLE9263-3BQXV33  
In case DLC is greater than 0, the data field of the received frame has at least one bit set in a bit position,  
where also in the configured data mask in the corresponding bit position the bit is set.  
No error exists according to ISO 11898-1 excepting errors which are signalled in the ACK field and EOF field.  
5.4.2.4 CAN Protocol Error Counter  
The counter is incremented, when a bit stuffing, CRC or form error according to ISO11898-1 is detected. If a  
frame has been received that is valid up to the end of the CRC field and the counter is not zero, the counter is  
decremented.  
If the counter has reached a value of 31, the following actions is performed on the next increment of this  
counter:  
The selective wake function is disabled,  
the CAN transceiver is woken,  
SYSERR is set and the error counter value = 32 can be read.  
On each increment or decrement of the counter the decoder unit waits for at least 6 and most 10 recessive bits  
before considering a dominant bit as new start of frame.  
The error counter is enabled:  
whenever the CAN is in Normal Mode, Receive Only Mode or in WUF detection state.  
The error counter is cleared under the following conditions:  
at the transition from WUF detection to WUP detection 1 (after tSILENCE expiration, while SWK is correctly  
enabled)  
When WUF detection state is entered (in this way the counter will start from 0 when SWK is enabled)  
At SBC or CAN rearming (when exiting the woken state)  
When the CAN Mode bits are selected ‘000’, ‘100’ (CAN OFF) or 0’01’ (Wake capable without SWK function  
enabled)  
While CAN_FD_EN = ‘1’ and DIS_ERR_CNT = ‘1’  
(the counter is cleared and stays cleared when these two bits are set in the SPI registers)  
The Error Counter is frozen:  
after a wake-up being in woken state  
The counter value can be read out of the bits ECNT.

5.4.3  
Diagnoses Flags  
5.4.3.1 PWRON/RESET-FLAG  
The power-on reset can be detected and read by the POR bit in the SBC Status register.  
The VS power on resets all register in the SBC to reset value. SWK is not configured.  
5.4.3.2 BUSERR-Flag  
Bus Dominant Time-out detection is implemented and signaled by CAN_Fail_x in register BUS_STAT_1.  
5.4.3.3 TXD Dominant Time-out flag  
TXD Dominant timeout is shown in the SPI bit CAN_FAIL_x in register BUS_STAT_1.  
5.4.3.4 WUP Flag  
The WUP bit in the SWK_STAT register shows that a Wake-Up Pattern (WUP) has caused a wake of the CAN  
transceiver. It can also indicate an internal mode change from WUP detection 1 state to WUF detection after a  
valid WUP.  
In the following case the bit is set:  
SWK is activated: due to tSILENCE, the CAN changes into the state WUP detection 1. If a WUP is detected in  
this state, then the WUP bit is set  
SWK is deactivated: the WUP bit is set if a WUP wakes up the CAN. In addition, the CAN_WU bit is set.  
in case WUP is detected during WUP detection 2 state (after a SYSERR) the bits WUP and CAN_WU are set  
The WUP bit is cleared automatically by the SBC at the next rearming of the CAN transceiver.  
Note:  
It is possible that WUF and WUP bit are set at the same time if a WUF causes a wake out of SWK, by  
setting the interrupt or by restart out of SBC Sleep Mode. The reason is because the CAN has been in  
WUP detection 1 state during the time of SWK mode (because of tSILENCE). See also Figure 11.  
5.4.3.5 WUF Flag (WUF)  
The WUF bit in the SWK_STAT register shows that a Wake-Up frame (WUF) has caused a wake of the CAN block.  
In SBC Sleep Mode this wake causes a transition to SBC Restart Mode, in SBC Normal Mode and in SBC Stop  
Mode it causes an interrupt. Also in case of this wake the bit CAN_WU in the register WK_STAT_1 is set.  
The WUF bit is cleared automatically by the SBC at the next rearming of the CAN SWK function.  
5.4.3.6 SYSERR Flag (SYSERR)  
The bit SYSERR is set in case of an configuration error and in case of an error counter overflow. The bit is only  
updated (set to ‘1’) if a CAN mode with SWK is enabled via CAN_x. If INT_ GLOBAL is set, then an interrupt is  
triggered on INTN every time SYSERR is set.  
When programming selective wake via CAN_x, SYSERR = ‘0’ signals that the SWK function has been enabled.  
The bit can be cleared via SPI. The bit is ‘0’ after Power on Reset of the SBC.  
5.4.3.7 Configuration Error  
A configuration error sets the SYSERR bit to ‘1’. When enabling SWK via the bits CAN_x a config check is done.  
If the check is successful SWK is enabled, the bit SYSERR is set to ‘0’. In SBC Normal Mode it is also possible to  
Datasheet

Rev. 1.2  
2022-05-04  
OPTIREG™ SBC TLE9263-3BQXV33  
detect a Configuration Error while SWK is enabled. This will occur if the CFG_VAL bit is cleared, e.g. by  
changing the SWK registers (from address 010 0001 to address 011 0011). In SBC Stop Mode and SBC Sleep  
Mode this is not possible as the SWK registers can not be changed.  
Configuration Check:  
in SBC Restart Mode, the CFG_VAL bit is cleared by the SBC. If the SBC Restart Mode was not triggered by a  
WUF wake up from SBC Sleep Mode and the CAN was with SWK enabled, than the SYSERR bit will be set.  
The SYSERR bit has to be cleared by the microcontroller.  
The SYSERR bit cannot be cleared when CAN_2 is ‘1’ and below conditions occur:  
Data valid bit not set by microcontroller, i.e. CFG_VAL is not set to ‘1’. The CFG_VAL bit is reset after SWK  
wake and needs to be set by the microcontroller before activation SWK again.  
CFG_VAL bit reset by the SBC when data are changed via SPI programming. (Only possible in SBC Normal  
Mode)  
Note:  
The SWK configuration is still valid if only the SWK_CTRL register is modified.  
5.4.3.8 CAN Bus Timeout-Flag (CANTO)  
In CAN WUF detection and CAN WUP detection 2 state the bit CANTO is set to ‘1’ if the time tSILENCE expires.  
The bit can be cleared by the microcontroller. If the interrupt function for CANTO is enabled then an interrupt  
is generated in SBC Stop or SBC Normal Mode when the CANTO set to ‘1’. The interrupt is enabled by setting  
the bit CANTO_ MASK to ‘1’. Each CANTO event will trigger a interrupt even if the CANTO bit is not cleared.  
There is no wake out of SBC Sleep Mode because of CAN time-out.  
5.4.3.9 CAN Bus Silence-Flag (CANSIL)  
In CAN WUF detection and CAN WUP detection 2 state the bit CANSIL is set to ‘1’ if the time tSILENCE expires.  
The CANSIL bit is set back to ‘0’ with a WUP. With this bit the microcontroller can monitor if there is activity on  
the CAN bus while being in SWK Mode. The bit can be read in SBC Stop and SBC Normal Mode.  
5.4.3.10 SYNC-FLAG (SYNC)  
The bit SYNC shows that SWK is working and synchronous to the CAN bus. To get a SYNC bit set it is required  
to enable the CAN to CAN Normal or in Receive Only Mode or in WUF detection. It is not required to enable the  
CAN SWK Mode.  
The bit is set to ‘1’ if a valid CAN frame has been received (no CRC error and no stuffing error). It is set back to  
‘0’ if a CAN protocol error is detected. When switching into SWK mode the SYNC bit indicates to the  
microcontroller that the frame detection is running and the next CAN frame can be detected as a WUF, CAN  
wake-up can now be handled by the SBC. It is possible to enter a SBC low-power mode with SWK even if the  
bit is not set to ‘1’, as this is necessary in case of a silent bus.  
5.4.3.11 SWK_SET FLAG (SWK_SET)  
The SWK_SET bit is set to signalize the following states (see also Figure 11):  
when SWK was correctly enabled in WUF Detection state,  
when SWK was correctly enabled when in WUP Detection 1 state,  
after a SYSERR before a wake event in WUP Detection 2 state,  
The bit is cleared under following conditions:  
after a wake-up (ECNT overflow, WUP in WUP detection 2, WUF in WUF detection)  
if CAN_2 is cleared

5.4.4  
SBC Modes for Selective Wake (SWK)  
The SBC mode is selected via the MODE bits as described in Chapter 5.1.  
The mode of the CAN transceiver needs to be selected in SBC Normal Mode. The CAN mode is programed the  
bits CAN_0, CAN_1 and CAN_2. In the low-power modes (SBC Stop, SBC Sleep) the CAN mode can not be  
changed via SPI.  
The detailed SBC state machine diagram including the CAN selective wake feature is shown in Figure 3.  
The application must now distinguish between the normal CAN operation an the selective wake function:  
WK Mode: This is the normal CAN wake capable mode without the selective wake function  
SWK Mode: This is the CAN wake capable mode with the selective wake function enabled  
Figure 14 shows the possible CAN transceiver modes.

In the CAN Normal Mode with SWK the CAN Transceiver works as in SBC Normal Mode, so bus data is received  
through RXD, data is transmitted through TXD and sent to the bus. In addition the SWK block is active. It

monitors the data on the CAN bus, updates the error counter and sets the CANSIL flag if there is no  
communication on the bus.  
It will generate an CAN Wake interrupt in case a WUF is detected (RXD is not pulled to LOW in this  
configuration).  
In CAN Receive Only Mode with SWK, CAN data can be received on RXD and SWK is active, no data can be sent  
to the bus.  
The bit SYSERR = ‘0’ indicates that the SWK function is enabled, and no frame error counter overflow is  
detected.

the bits SYSERR, SWK_SET and CAN have to be evaluated. A change out of SBC Normal Mode can change the  
CAN_0 and CAN_1 bits.  
5.4.4.2 SBC Stop Mode with SWK  
In SBC Stop Mode the CAN Transceiver can be operated with the following CAN Modes  
CAN OFF  
CAN WK Mode (no SWK)  
CAN SWK Mode  
CAN Receive Only (no SWK)  
CAN Receive Only with SWK  
CAN Normal Mode (no SWK)  
CAN Normal Mode with SWK  
To enable CAN SWK Mode the CAN has to be switched to “CAN Normal Mode with SWK”, “CAN Receive Only  
Mode with SWK” or to “CAN SWK Mode” in SBC Normal Mode before sending the SBC to SBC Stop Mode. The  
bit SYSERR = ‘0’ indicates that the SWK function is enabled. The table shows the change of CAN Mode when  
switching from SBC Normal Mode to SBC Stop Mode.  
Note:  
CAN Receive Only Mode in SBC Stop Mode is implemented to also enable pretended networking  
(Partial networking done in the microcontroller).

Note:  
When SYSERR is set then WUF frames will not be detected, i.e. the selective wake function is not  
activated (no SWK), but the MSB of CAN mode is not changed in the register.  
5.4.4.3 SBC Sleep Mode with SWK  
In SBC Sleep Mode the CAN Transceiver can be switched into the following CAN Modes  
CAN OFF  
CAN WK Mode (without SWK)  
CAN SWK Mode  
To enable “CAN SWK Mode” the CAN has to be switched to “CAN Normal Mode with SWK”, “CAN Receive Only  
Mode with SWK” or to “CAN SWK Mode” in SBC Normal Mode before sending the device to SBC Sleep Mode.  
The table shows the change of CAN mode when switching from SBC Normal Mode to Sleep Mode.  
A wake from Sleep Mode with Selective Wake (Valid WUF) leads to Restart Mode. In Restart Mode the CFG_VAL  
bit will be cleared by the SBC, the SYSERR bit is not set. In the register CAN_x the programmed CAN SWK Mode  
(101) can be read.  
To enable the CAN SWK Mode again and to enter SBC Sleep Mode the following sequence can be used;  
Program a CAN Mode different from CAN SWK Mode (101, 110, 111), set the CFG_VAL, CLEAR SYSERR bit, Set  
CAN_x bits to CAN SWK Mode (101), switch SBC to Sleep Mode.  
To enable the CAN WK Mode or CAN SWK Mode again after a wake on CAN a rearming is required for the CAN  
transceiver to be wake capable again. The rearming is done by programming the CAN into a different mode  
with the CAN_x bit and back into the CAN WK Mode or CAN SWK Mode. To avoid lock-up when switching the  
SBC into Sleep Mode with an already woken CAN transceiver, the SBC does an automatic rearming of the CAN  
transceiver when switching into Sleep Mode. So after switching into Sleep Mode the CAN transceiver is either  
in CAN SWK Mode or CAN WK Mode depending on CAN_x setting and SYSERR bit (If CAN is switched to OFF  
Mode it is also OFF in Sleep Mode)

1) In case there is a WUF detection within tSILENCE then the WUP bit will not be set. Otherwise it will always be set together

5.4.4.5 SBC Fail-Safe Mode with SWK  
When SBC Fail-Safe Mode is entered the CAN transceiver is automatically set into WK Mode (wake capable)  
without the selective wake function.  
5.4.5  
Wake-up  
A wake-up via CAN leads to a restart out of SBC Sleep Mode and to an interrupt in SBC Normal Mode, and in  
SBC Stop Mode. After the wake event the bit CAN_WU is set, and the details about the wake can be read out of  
the bits WUP, WUF, SYSERR, and ECNT.  
5.4.6  
Configuration for SWK  
The CAN protocol handler settings can be configured in following registers:  
SWK_BTL1_CTRL defines the number of time quanta in a bit time. This number depends also on the  
internal clock settings performed in the register SWK_CDR_CTRL2;  
SWK_BTL2_CTRL defines the sampling point position;  
The respective receiver during frame detection mode can be selected via the bit RX_WK_ SEL;  
The clock and data recovery (see also Chapter 5.4.8) can be configured in the registers SWK_CDR_CTRL1,  
SWK_CDR_CTRL2, SWK_CDR_LIMIT_HIGH_CTRL and SWK_CDR_LIMIT_LOW_CTRL;

The actual configuration for selective wake is done via the Selective Wake Control Registers SWK_IDx_CTRL,  
SWK_MASK_IDx_CTRL, SWK_DLC_CTRL, SWK_DATAx_CTRL.  
The oscillator has the option to be trimmed by the microcontroller. To measure the oscillator, the SPI bit  
OSC_CAL needs to be set to 1 and a defined pulse needs to be given to the TXDCAN pin by the microcontroller  
(e.g. 1µs pulse, CAN needs to be switched off before). The SBC measures the length of the pulse by counting  
the time with the integrated oscillator. The counter value can be read out of the register  
SWK_OSC_CAL_H_STATE and SWK_OSC_CAL_L_STATE. To change the oscillator the trimming function needs  
to be enabled by setting the bits TRIM_EN_x = 11 (and OSC_CAL = 1). The oscillator can then be adjusted by  
writing into the registers SWK_OSC_TRIM_CTRL and SWK_OPT_CTRL. To finish the trimming, the bits  
TRIM_EN_x need to be set back to “00”.

5.4.7  
CAN Flexible Data Rate (CAN FD) Tolerant Mode  
The CAN FD tolerant mode can be activated by setting the bit CAN_FD_ EN = ‘1’ in the register  
SWK_CAN_FD_CTRL. With this mode the internal CAN frame decoding will be stopped for CAN FD frame  
formats:  
The high baudrate part of a CAN FD frame will be ignored,  
No Error Handling (Bit Stuffing, CRC checking, Form Errors) will be applied to remaining CAN frame fields  
(Data Field, CRC Field, …),  
No wake up is done on CAN FD frames.  
The internal CAN frame decoder will be ready for new CAN frame reception when the End of frame (EOF) of a  
CAN FD frame is detected.The identification for a CAN FD frame is based on the FDF Bit, which is sent in the  
Control Field of a CAN FD frame:  
.
FDF Bit = 1 identifies the current frame as an CAN FD frame and will stop further decoding on it.  
FDF Bit = 0 identifies the current frame as CAN 2.0 frame and processing of the frame will be continued  
In this way it is possible to send mixed CAN frame formats without affecting the selective wake functionality  
by error counter increment and subsequent misleading wake up.In addition to the CAN_FD_ EN bit also a filter  
setting must be provided for the CAN FD tolerant mode. This filter setting defines the minimum dominant time  
for a CAN FD dominant bit which will be considered as a dominant bit from the CAN FD frame decoder. This  
value must be aligned with the selected high baudrate of the data field in the CAN network.  
To support programming via CAN during CAN FD mode a dedicated SPI bit DIS_ERR_ CNT is available to avoid  
an overflow of the implemented error counter (see also Chapter 5.4.2.4).  
The behavior of the error counter depends on the setting of the bits DIS_ERR_ CNT and CAN_FD_ EN and is  
show in below table:

5.4.8  
Clock and Data Recovery  
In order to compensate possible deviations on the CAN oscillator frequency caused by assembly and lifetime  
effects, the device features an integrated clock and data recovery (CDR).  
It is recommended to always enable the CDR feature during SWK operation.  
5.4.8.1 Configuring the Clock Data Recovery for SWK  
The Clock and Data Recovery can be optionally enabled or disabled with the CDR_EN bit in the  
SWK_CDR_CTRL1 SPI register. In case the feature is enabled, the CAN bit stream will be measured and the  
internal clock used for the CAN frame decoding will be updated accordingly.  
Before the Clock and Data Recovery can be used it must be configured properly related to the used baud rate  
and filtering characteristics (see Chapter 5.4.8.2).  
It is strongly recommended not to enable/disable the Clock Recovery during a active CAN Communication.  
To ensure this, it is recommended to enable/disable it during CAN OFF (BUS_CTRL_1; CAN[2:0] = 000).

5.4.8.2 Setup of Clock and Data Recovery  
It is strongly recommended to enable the clock and data recovery feature only when the setup of the clock and  
data recovery is finished.  
The following sequence should be followed for enabling the clock and data recovery feature:  
Step 1: Switch CAN to OFF and CDR_EN to OFF  
Write SPI Register BUS_CTRL_1 (CAN[2:0] = 000).  
Step 2: Configure CDR Input clock frequency  
Write SPI Register SWK_CDR_CTRL2 (SEL_OSC_CLK[1:0]).  
Step 3: Configure Bit timing Logic  
Write SPI Register SWK_BTL1_CTRL and adjust SWK_CDR_LIMIT_HIGH_CTRL and  
SWK_CDR_LIMIT_LOW_CTRL according to Table 38.  
Step 4: Enable Clock and Data Recovery  
Choose filter settings for Clock and Data recovery. Write SPI Register SWK_CDR_CTRL1 with CDR_EN = 1  
Additional hints for the CDR configuration and operation:  
Even if the CDR is disabled, when the baud rate is changed, the settings of SEL_OSC_CLK in the register  
SWK_CDR_CTRL1 and SWK_BTL1_CTRL have to be updated accordingly,  
The SWK_CDR_LIMIT_HIGH_CTRL and SWK_CDR_LIMIT_LOW_CTRL registers have to be also updated  
when the baud rate or clock frequency is changed (the CDR is discarding all the acquisitions and looses all  
acquired information, if the limits are reached - the SWK_BTL1_CTRL value is reloaded as starting point  
for the next acquisitions)  
When updating the CDR registers, it is recommended to disable the CDR and to enable it again only after  
the new settings are updated,  
The SWK_BTL2_CTRL register represents the sampling point position. It is recommended to be used at  
default value: 11 0011 (~80%)

Voltage Regulator 1  
6.2  
Functional Description  
The Voltage Regulator 1 (=VCC1) is “ON” in SBC Normal and SBC Stop Mode and is disabled in SBC Sleep and  
in SBC Fail-Safe Mode. The regulator can provide an output current up to IVCC1,lim  
.
For low-quiescent current reasons, the output voltage tolerance is decreased in SBC Stop Mode because only  
a low-power mode regulator with a lower accuracy (VCC1,out71) will be active for small loads. If the load current  
on VCC1 exceeds the selected threshold (IVCC1,Ipeak1,r or IVCC1,Ipeak2,r) then the high-power mode regulator will be  
also activated to support an optimum dynamic load behavior. The current consumption will then increase by  
typ. 2.9mA.  
If the load current on VCC1 falls below the selected threshold (IVCC1,Ipeak1,f or IVCC1,Ipeak2,f), then the low-quiescent  
current mode is resumed again by disabling the high-power mode regulator.  
Both regulators (low-power mode and high-power mode) are active in SBC Normal Mode.  
Two different active peak thresholds can be selected via SPI:  
I_PEAK_TH = ‘0’(default): the lower VCC1 active peak threshold 1 is selected with lowest quiescent current  
consumption in SBC Stop Mode (IStop_1,25, IStop_1,85);  
I_PEAK_TH = ‘1’: the higher VCC1 active peak threshold 2 is selected with an increased quiescent current  
consumption in SBC Stop Mode (IStop_2,25, IStop_2,85);

Functional Description  
In SBC Normal Mode VCC2 can be switched on or off via SPI.  
For SBC Stop- or Sleep Mode, the VCC2 has to be switched on or off before entering the respective SBC mode.  
The regulator can provide an output current up to IVCC2,lim  
.
For low-quiescent current reasons, the output voltage tolerance is decreased in SBC Stop Mode because only  
a low-power mode regulator with a lower accuracy (VCC2,out5) will be active for small loads. If the load current  
on VCC2 exceeds IVCC2 > IVCC2,Ipeak,r then the high-power mode regulator will also be enabled to support an  
optimum dynamic load behavior. The current consumption will then increase by typ. 2.9mA.  
If the load current on VCC2 falls below the threshold (IVCC2 < IVCC2,Ipeak,f), then the low-quiescent current mode  
is resumed again by disabling the high-power mode regulator.  
Both regulators are active in SBC Normal Mode.  
Note:  
If the VCC2 output voltage is supplying external off-board loads, the application must consider the  
series resonance circuit built by cable inductance and decoupling capacitor at the load. Sufficient  
damping must be provided.

Functional Description  
The external voltage regulator can be used as an independent voltage regulator or in load-sharing mode with  
VCC1. Setting VCC3_ON in the M_S_CTRL register in SBC Normal Mode sets the stand-alone configuration of  
VCC3 as an independent voltage regulator. The load sharing configuration is set via the SPI bit VCC3_LS in the  
HW_CTRL register.

Figure 23 Selecting the Configuration of the VCC3 Regulator  
Depending on the configuration the regulator will act in the respective SBC Mode as described in Table 19.  
After the VCC3 configuration has been selected, it cannot be changed anymore.  
In stand-alone configuration the maximum current ICC3max is defined by the current limitation determined by  
the used shunt. In load sharing configuration, the shunt is used to determine the current ratio between VCC1  
and VCC3. Since the junction temperature of the external PNP transistor cannot be sensed by the SBC, it  
cannot be protected against overtemperature by the SBC. Therefore the thermal behavior has to be analyzed  
by the application.  
For low-quiescent current reasons, the output voltage tolerance is decreased in SBC Stop Mode because a  
low-power mode regulator with a lower accuracy will be active for small loads. If the base current on VCC3  
exceeds IVCC3base > IVCC3base,Ipeak,r then the high-power mode regulator is enabled additionally to support an  
optimum dynamic load behavior. If the base current on VCC3 falls below the threshold (IVCC3base  
<
IVCC3base,Ipeak,f), then the low-quiescent current consumption is resumed again by disabling the high-power  
mode regulator.  
Only the high-power mode regulator is active in SBC Normal Mode.  
The status of VCC3 is reported in the SUP_STAT_2 SPI register. The regulator will switch OFF in case of VS  
dropping below VS_UV regardless of the VCC3 configuration and will be automatically enabled again when  
exceeding this threshold voltage unless the control bit VCC3_VS_ UV_OFF is set, i.e. in order to keep VCC3

enabled below VS_UV the bit VCC3_VS_ UV_OFF must be set. VCC3 will also stay active in SBC Stop Mode  
when the bit VCC3_LS_ STP_ON is set and when load sharing is configured (for detailed protection features  
see Chapter 15.7 and Chapter 16.3).

2) Load Sharing operation in SBC Stop Mode is by default disabled for power saving reasons but VCC3_LS bit will stay  
set. However, it can be also configured via the SPI bit VCC3_LS_ STP_ON to stay enabled in SBC Stop Mode.  
Notes  
1. The configuration of the VCC3 voltage regulator behavior must be done immediately after power-up of the  
device and cannot be changed afterwards as long as the device is supplied.  
2. As soon as the bit VCC3_ON or VCC3_LS is set for the first time, the configuration for VCC3 cannot be changed  
anymore. This configuration is valid - also after a SBC Soft Reset - as long as the SBC is powered.  
3. If the VCC3 output voltage is supplying external off-board loads, the application must consider the series  
resonance circuit built by cable inductance and decoupling capacitor at the load. Sufficient damping must be  
provided (e.g. a 100Ohm resistor between the PNP collector and VCC3REF with 10uF capacitor on collector -  
see also Figure 24).  
8.2.1  
External Voltage Regulator as Independent Voltage Regulator  
Configured as an independent voltage regulator the SBC offers with VCC3 a third supply which could be used  
as off-board supply e.g. for sensors due to the integrated HV pins VCC3B, VCC3SH, VCC3REF.  
This configuration is set and locked by enabling VCC3_ON while keeping VCC3_LS = 0. VCC3 can be switched  
ON or OFF but the configuration cannot be changed anymore. However, the SPI_FAIL is not set while trying to  
change the configuration.  
An overcurrent limitation function is realized with the external shunt (see Chapter 8.4 for calculating the  
desired shunt value) and the output current shunt voltage threshold (Vshunt_threshold). If this threshold is  
reached, then ICC3 is limited and only the current limitation bit VCC3_OC is set (no other reaction) and can be  
cleared via SPI once the overcurrent condition is not present anymore. If the overcurrent limitation feature is  
not needed, then connect the pins VCC3SH and VS together.  
In this configuration VCC3 has the undervoltage signalization enabled and an undervoltage event is signaled  
with the bit VCC3_UV in the SUP_STAT_2 SPI register.  
Note:  
To avoid undesired current consumption increase of the device it must be ensured that VCC3 is not  
connected to VCC1 in this configuration.

8.2.2  
External Voltage Regulator in Load Sharing Mode  
The purpose of the load sharing mode is to increase the total current capability of VCC1 without increase of  
the power dissipation within the SBC. The load current is shared between the VCC1 internal regulator and the  
external PNP transistor of VCC3. Figure 25 shows the setup for Load Sharing. Load Sharing is active in SBC  
Normal Mode. It can also be configured via SPI to stay active in SBC Stop Mode.  
An input voltage up to VSx,MAX is regulated to VCC3,nom = 3.3 V with a precision of ±2% when used in the load  
sharing configuration in SBC Normal Mode.  
This configuration is set and locked by enabling VCC3_LS for the first time while VCC3_ON has no function, i.e.  
keep VCC3_ON = 0. Trying to change the VCC3 configuration after VCC3_LS has been set will result in the  
SPI_FAIL bit being set and keeping the VCC3 configurations unchanged. Load sharing will be automatically  
disabled (only if VCC3_LS_ STP_ON = 0) during SBC Stop Mode due to power saving reasons but the bit will  
remain set to automatically switch back on after returning to SBC Normal Mode. It must be ensured that the  
same VCC3 output voltage level is selected as for VCC1.  
In this configuration VCC3 has no undervoltage signalization. VCC3 shuts down if Fail-Safe Mode is reached,  
e.g. due to undervoltage shutdown (VS,UV monitoring).  
VCC3 has no overcurrent limitation in this configuration and the shunt resistor is defining the load sharing  
ratio between the VCC1 and VCC3 load currents (see Equation (8.2) in Chapter 8.4). Thus, no overcurrent  
condition VCC3_OC will be signaled in this configuration.

Note:  
The SBC is not able to ensure a thermal protection of the external PNP transistor. The power  
handling capabilities for the application must therefore be chosen according to the selected PNP  
device, the PCB layout and properties of the application to prevent thermal damage, e.g. via the  
shunt current limitation in stand alone configuration or by selecting the proper ICC1/ICC3 ratio in  
load-sharing configuration.  
Note:  
To ensure an optimum EMC behavior of the VCC3 regulator when the VCC3 output is leaving the PCB,  
it is necessary to optimize the PCB layout to have the PNP very close to the SBC. If this is not sufficient  
or possible, an external capacitance should be placed to the off-board connector (see also  
Chapter 17.1).

Calculation of RSHUNT  
As a independent regulator, the maximum current ICC3max where the limit starts and the bit ICC3 > ICC3max is set is  
determined by the shunt resistor RSHUNT and the Output Current Shunt Voltage Threshold Vshunt_threshold  
.
The resistor can be calculated as following:  
Ushunt _ threshold  
(8.1)  
RSHUNT

ICC3 max  
If VCC3 is configured for load sharing, then the shunt resistor determines the load sharing ratio between VCC1  
and VCC3. The ratio can be calculated as following:

Example: A shunt resistor with 470mand a load current of 100mA out of VCC1 would result in ICC3 = 191mA.

Unused Pins  
In case the VCC3 is not used in the application, it is recommended to connect the unused pins of VCC3 as  
followed:  
Connect VCC3SH to VS or leave open;  
Leave VCC3B open;  
Leave VCC3REF open  
Do not enable the VCC3 via SPI as this leads to increased current consumption

3) At Tj > 125°C, the power transistor leakage could be increased, which has to be added to the quiescent current of the  
application independently if the regulator is turned on/off. To prevent an overvoltage condition at no load due to this  
increased leakage, an internal clamping structure will automatically turn on at typ. 200mV above the upper limit of the  
programmed output voltage.  
4) IVCC3_peak refers to the load current out of the collector of the external PNP device. This value can be calculated by  
multiplying the VCC3base active peak threshold (IVCC3base,Ipeak) with the current gain of the PNP  
5) Not subject to production test, specified by design.  
6) a) Ratio will change depending on the chosen shunt resistor which value is correlating to the maximum power  
dissipation of the PNP pass device. See Chapter 8.4 for the ratio calculation. The ratio will also change at low-drop  
operation.  
For supply voltages of 5.5V < VS < 6V the accuracy applies only for a total load current of 250mA.  
The load sharing ratio in SBC Stop Mode has +/-10% wider limits than specified.  
b) The output voltage precision in load sharing in SBC Stop Mode is according to VCC1 +/-4% or better for loads up to  
20mA and +/-2% with loads greater than 20mA.  
In SBC Normal the +/-2% precision for 5V/3.3V tolerance is valid regardless of the applied load.  
Notes  
1. There is no thermal protection available for the external PNP transistor. Therefore, the application must be  
designed to avoid overheating of the PNP via the shunt current limitation in stand alone configuration and by  
selecting the proper ICC1/ICC3 ratio in load-sharing configuration.  
2. In SBC Stop Mode, the same output voltage tolerance applies as in SBC Normal Mode when IVCC3 has exceeded  
the selected active peak threshold (IVCC3base,Ipeak) but with increased current consumption.

Functional Description  
The High-Side switches can be used for control of LEDs, as supply for the wake inputs and for other loads. The  
High-Side outputs can be controlled either directly via SPI by (HS_CTRL1, HS_CTRL2), by the integrated  
timers or by the integrated PWM generators.  
The high-side outputs are supplied by a dedicated supply pin VSHS (different to VS). The topology supports  
improved cranking condition behavior.  
The configuration of the High-Side (Permanent On, PWM, cyclic sense, etc.) drivers must be done in SBC  
Normal Mode. The configuration is taken over in SBC Stop- or SBC Sleep Mode and cannot be modified. When  
entering SBC Restart Mode or SBC Fail-Safe Mode the HSx outputs are disabled.

OPTIREG™ SBC TLE9263-3BQXV33  
High-Side Switch  
9.2.1  
Over- and Undervoltage Switch Off  
All HS drivers in on-state are switched off in case of overvoltage on VSHS (VSHS,OVD). If the voltage drops below  
the overvoltage threshold the HS drivers are activated again. The feature can be disabled by setting the SPI bit  
HS_OV_SD_EN.  
The HS drivers are switched off in case of undervoltage on VSHS (VSHS,UVD). If the voltage rises above the  
undervoltage threshold the HS drivers are activated again. The feature can be disabled by setting the SPI bit  
HS_UV_SD_EN.  
So after release of undervoltage or overvoltage condition the HS switch goes back to programmed state in  
which it was configured via SPI. This behavior is only valid if the bit HS_OV_UV_REC is set to ‘1’. Otherwise the  
switches will stay off and the respective SPI control bits are cleared.  
The overvoltage and undervoltage is signaled in the bits VSHS_OV and VSHS_UV, no other error bits are set.  
9.2.2  
Overcurrent Detection and Switch Off  
If the load current exceeds the overcurrent shutdown threshold for a time longer then the overcurrent  
shutdown filter time the output is switched off.  
The overcurrent condition and the switch off is signaled with the respective HSx_OC_OT bit in the register  
HS_OC_OT_STAT. The HSx configuration is then reset to 000 by the SBC. To activate the High-Side again the  
HSx configuration has to be set to ON (001) or be programmed to a timer function. It is recommended to clear  
the overcurrent bit before activation the High-Side switch, as the bits are not cleared automatically by the  
SBC.  
9.2.3  
Open Load Detection  
Open load detection on the High-Side outputs is done during on state of the output. If the current in the  
activated output falls below then Open Load Detection current, the open load is detected and signaled via the  
respective bit HS1_OL, HS2_OL, HS3_OL, or HS4_OL in the register HS_OL_STAT. The High-Side output stays  
activated. If the open load condition disappears the Open Load bit in the SPI can be cleared. The bits are not  
cleared automatically by the SBC.  
9.2.4  
HSx Operation in Different SBC Modes  
During SBC Stop and SBC Sleep Mode the HSx outputs can be used for the cyclic sense feature. The open-  
load detection, overcurrent shut down as well as overvoltage and undervoltage shutdown are available.  
The overcurrent shutdown protection feature may influence the wake-up behavior1).  
the HSx output can also be enabled for SBC Stop and SBC Sleep Mode as well as controlled by the PWMx  
generator. The HSx outputs must be configured in SBC Normal Mode before entering a low-power mode.  
The HSx outputs are switched off during SBC Restart or SBC Fail-Safe Mode. They can be enabled via SPI if  
the failure condition is removed.  
9.2.5  
PWM and Timer Function  
Two 8-bit PWM generators are dedicated to generate a PWM signal on the HS outputs, e.g. for brightness  
adjustment or compensation of supply voltage fluctuation. The PWM generators are mapped to the dedicated  
HS outputs, and the duty cycle can be independently configured with a 8bit resolution via SPI (PWM1_CTRL,  
1) For the wake feature, the forced overcurrent shut down case must be considered in the user software for all SBC Modes, i.e. due to  
disabled HSx switches a level change might not be detected anymore at WKx pins.

Minimum On-time during PWM Operation  
The min. on-time during PWM is limited by the actual on- and off-time of the respective HS switch, e.g. the  
PWM setting ‘0000 0001’ could not be realized.  
Reliable Open-Load Detection during PWM Operation  
The minimum PWM setting for a reliable open-load detection is 3digits for a period of 400Hz and >2 digits for  
the frequency setting of 200Hz, i.e. the high-side on-time must be longer than tOL,HS  
.
Reliable Overcurrent Detection during PWM Operation  
The minimum PWM setting for a reliable overcurrent detection is >1 digit for a period of 400Hz and 1 digit for  
the frequency setting of 200Hz, i.e. the high-side on-time must be longer than tSD,HS  
.

Functional Description  
The Controller Area Network (CAN) transceiver part of the SBC provides high-speed (HS) differential mode  
data transmission (up to 2 Mbaud) and reception in automotive and industrial applications. It works as an  
interface between the CAN protocol controller and the physical bus lines compatible to ISO 11898-2:2016 and  
SAE J2284.  
The CAN transceiver offers low power modes to reduce current consumption. This supports networks with  
partially powered down nodes. To support software diagnostic functions, a CAN Receive-only Mode is  
implemented.  
It is designed to provide excellent passive behavior when the transceiver is switched off (mixed networks,  
clamp15/30 applications).  
A wake-up from the CAN wake capable mode is possible via a message on the bus. Thus, the microcontroller  
can be powered down or idled and will be woken up by the CAN bus activities.  
The CAN transceiver is designed to withstand the severe conditions of automotive applications and to support  
12 V applications.

will remain OFF.  
Behavior in SBC Development Mode:

CAN FD Support  
CAN FD stands for ‘CAN with Flexible Data Rate’. It is based on the well established CAN protocol as specified  
in ISO 11898-1. CAN FD still uses the CAN bus arbitration method. The benefit is that the bit rate can be  
increased by switching to a shorter bit time at the end of the arbitration process and then to return to the  
longer bit time at the CRC delimiter, before the receivers transmit their acknowledge bits. See also Figure 32.  
In addition, the effective data rate is increased by allowing longer data fields. CAN FD allows the transmission  
of up to 64 data bytes compared to the 8 data bytes from the standard CAN.

Not only the physical layer must support CAN FD but also the CAN controller. In case the CAN controller is not  
able to support CAN FD then the respective CAN node must at least tolerate CAN FD communication. This  
CAN FD tolerant mode is realized in the physical layer in combination with CAN Partial Networking.

High Speed CAN Transceiver  
The TLE926x-3BQX variants of this family also support the CAN FD tolerant mode. See also Chapter 5.4.7 for  
more detailed information on how to enable the CAN FD tolerant mode.  
10.2.1  
CAN OFF Mode  
The CAN OFF Mode is the default mode after power-up of the SBC. It is available in all SBC Modes and is  
intended to completely stop CAN activities or when CAN communication is not needed. The CANH/L bus  
interface acts as a high impedance input with a very small leakage current. In CAN OFF Mode, a wake-up event  
on the bus will be ignored.  
10.2.2  
CAN Normal Mode  
The CAN Transceiver is enabled via SPI in SBC Normal Mode. CAN Normal Mode is designed for normal data  
transmission/reception within the HS-CAN network. The Mode is available in SBC Normal Mode and in SBC  
Stop Mode. The bus biasing is set to VCAN/2.  
Transmission  
The signal from the microcontroller is applied to the TXDCAN input of the SBC. The bus driver switches the  
CANH/L output stages to transfer this input signal to the CAN bus lines.  
Enabling sequence  
The CAN transceiver requires an enabling time tCAN,EN before a message can be sent on the bus. This means  
that the TXDCAN signal can only be pulled LOW after the enabling time. If this is not ensured, then the TXDCAN  
needs to be set back to HIGH (=recessive) until the enabling time is completed.  
Only the next dominant bit will be transmitted on the bus.  
Figure 33 shows different scenarios and explanations for CAN enabling.

10.2.3  
CAN Receive Only Mode  
In CAN Receive Only Mode (RXD only), the driver stage is de-activated but reception is still operational. This  
mode is accessible by an SPI command in Normal Mode and in Stop Mode. The bus biasing is set to VCAN/2.  
10.2.4  
CAN Wake Capable Mode  
This mode can be used in SBC Stop, Sleep, Restart and Normal Mode and it is used to monitor bus activities.  
It is automatically accessed in SBC Fail-Safe Mode. Both bus pins CANH/L are connected to GND via the input  
resistors.  
A wake-up signal on the bus results in a change of behavior of the SBC, as described in Table 23. The pins  
CANH/L are terminated to typ. 2.5V through the input resistors. As a wake-up signalization to the  
microcontroller, the RXD_CAN pin is set LOW and will stay LOW until the CAN transceiver is changed to any  
other mode. After a wake-up event, the transceiver can be switched to CAN Normal Mode for communication  
via SPI.  
As shown in Figure 34, a wake-up pattern (WUP) is signaled on the bus by two consecutive dominant bus  
levels for at least tWake1 (filter time t > tWake1) and shorter than tWake2, each separated by a recessive bus level  
of greater than tWake1 and shorter than tWake2  
.

Rearming the Transceiver for Wake Capability  
After a BUS wake-up event, the transceiver is woken. However, the CAN transceiver mode bits will still show  
wake capable (=‘01’) so that the RXD signal will be pulled low. There are two possibilities how the CAN  
transceiver’s wake capable mode is enabled again after a wake event:  
The CAN transceiver mode must be toggled, i.e. switched from Wake Capable Mode to CAN Normal Mode,  
CAN Receive Only Mode or CAN Off, before switching to CAN Wake Capable Mode again.  
Rearming is done automatically when the SBC is changed to SBC Stop or SBC Fail-Safe Mode to ensure  
wake-up capability.  
CAN must be set to CAN wake capable / CAN off mode before entering SBC Sleep Mode  
Notes  
1. It is not necessary to clear the CAN wake-up bit CAN_WU to become wake capable again. It is sufficient to  
toggle the CAN mode.  
2. The CAN module is supplied by an internal voltage when in CAN Wake Capable Mode, i.e. the module does not  
need to be supplied by the VCAN pin during this time. Before changing the CAN Mode to Normal Mode, the  
supply of VCAN has to be activated first.

OPTIREG™ SBC TLE9263-3BQXV33  
High Speed CAN Transceiver  
Wake-Up in SBC Stop and Normal Mode  
In SBC Stop Mode, if a wake-up is detected, it is always signaled by the INT output and in the WK_STAT_1 SPI  
register. It is also signaled by RXDCAN pulled to low. The same applies for the SBC Normal Mode. The  
microcontroller should set the device from SBC Stop Mode to SBC Normal Mode, there is no automatic  
transition to Normal Mode.  
For functional safety reasons, the watchdog will be automatically enabled in SBC Stop Mode after a Bus wake  
event in case it was disabled before (if bit WD_EN_ WK_BUS was configured to HIGH before).  
Wake-Up in SBC Sleep Mode  
Wake-up is possible via a CAN message (filter time t > tWake1). The wake-up automatically transfers the SBC into  
the SBC Restart Mode and from there to Normal Mode the corresponding RXD pin in set to LOW. The  
microcontroller is able to detect the low signal on RXD and to read the wake source out of the WK_STAT_1  
register via SPI. No interrupt is generated when coming out of Sleep Mode. The microcontroller can now for  
example switch the CAN transceiver into CAN Normal Mode via SPI to start communication.

TXD Time-out Feature  
If the TXD signal is dominant for a time t > tTXD_CAN_TO, in CAN Normal Mode, the TXD time-out function  
deactivates the transmission of the signal at the bus. This is implemented to prevent the bus from being  
blocked permanently due to an error. The transmitter is disabled and the transceiver is switched to Receive  
Only Mode. The failure is stored in the SPI flag CAN_FAIL. The CAN transmitter stage is activated again after  
the dominant time-out condition is removed and the transceiver is automatically switched back to CAN  
Normal Mode. The transceiver configuration stays unchanged.  
10.2.6  
Bus Dominant Clamping  
If the HS CAN bus signal is dominant for a time t > tBUS_CAN_TO in CAN Normal and Receive Only Mode a bus  
dominant clamping is detected and the SPI bit CAN_FAIL is set. The transceiver configuration stays  
unchanged.  
10.2.7  
Undervoltage Detection  
The voltage at the CAN supply pin is monitored only in CAN Normal and Receive Only Mode for SBC Normal  
and Stop Mode . In case of VCAN undervoltage a signalization via SPI bit VCAN_UV is triggered and the SBC  
disables the transmitter stage. If the CAN supply reaches a higher level than the undervoltage detection  
threshold (VCAN > VCAN_UV), the transceiver is automatically switched back to CAN Normal Mode. The  
transceiver configuration stays unchanged.

LIN Specifications  
The LIN network is standardized by international regulations.  
The device is compliant to the physical layer standard LIN 2.2/ISO 17987-4 and SAE J2602-2. The SAE J2602-2  
standard differs from the LIN 2.2/ISO 17987-4 standard mainly by the lower data rate (10.4 kbit/s).

LIN Transceiver  
11.2  
Functional Description  
The LIN Bus is a single wire, bi-directional bus, used for in-vehicle networks. The LIN transceivers implemented  
inside the TLE9263-3BQXV33 are the interface between the micro controller and the physical LIN Bus. The  
digital output data from the micro controller are driven to the LIN bus via the TXD input pin on the TLE9263-  
3BQXV33. The transmit data stream on the TXD input is converted to a LIN bus signal with optimized slew rate  
to minimize the EME level of the LIN network. The RXD output sends back the information from the LIN bus to  
the micro controller. The receiver has an integrated filter network to suppress noise on the LIN Bus and to  
increase the EMI (Electro Magnetic Immunity) level of the transceiver.  
Two logical states are possible on the LIN Bus according to LIN 2.2/ISO 17987-4.  
Every LIN network consists of a master node and one or more slave nodes. To configure the TLE9263-3BQXV33  
for master node applications, a resistor in the range of 1 kand a reverse diode must be connected between  
the LIN bus and the power supply VSHS.  
The different transceiver modes can be controlled via the SPI and LIN2 bits.  
Figure 38 shows the possible transceiver mode transitions when changing the SBC mode.

Behavior after SBC Restart Mode - not coming from SBC Sleep Mode due to a wake up of the respective transceive:r  
If the transceivers had been configured to Normal Mode, or Receive Only Mode, then the mode will be changed to Wake  
Capable. If it was Wake Capable, then it will remainWake Capable. If it had been OFF before SBC Restart Mode, then it  
will remain OFF.  
Behavior in SBC Development Mode:  
LIN default value in SBC INIT MODE and entering SBC Normal Mode from SBC Init Mode is ON instead of OFF.  
Figure 38 LIN Mode Control Diagram  
11.2.1  
LIN OFF Mode  
The LIN OFF Mode is the default mode after power-up of the SBC. It is available in all SBC Modes and is  
intended to completely stop LIN activities or when LIN communication is not needed. In LIN OFF Mode, a  
wake-up event on the bus will be ignored.

11.2.2  
LIN Normal Mode  
The LIN Transceiver is enabled via SPI in SBC Normal Mode. LIN Normal Mode is designed for normal data  
transmission/reception within the LIN network. The Mode is available in SBC Normal Mode and in SBC Stop  
Mode.  
Transmission  
The signal from the microcontroller is applied to the TXDLIN input of the SBC. The bus driver switches the  
LIN output stage to transfer this input signal to the LIN bus line.  
Enabling Sequence  
The LIN transceiver requires an enabling time tLIN,EN before a message can be sent on the bus. This means that  
the TXDLIN signal can only be pulled LOW after the enabling time. If this is not ensured, then the TXDLIN needs  
to be set back to high (=recessive) until the enabling time is completed.  
Only the next dominant bit will be transmitted on the bus.  
Figure 39 shows different scenarios and explanations for LIN enabling.

Reduced Electromagnetic Emission  
To reduce electromagnetic emissions (EME), the bus driver controls LIN slopes symmetrically. The  
configuration of the different slopes is described in Chapter 11.2.8.  
Reception  
Analog LIN bus signals are converted into digital signals at RXD via the differential input receiver.  
11.2.3  
LIN Receive Only Mode  
In LIN Receive Only Mode (RXD only), the driver stage is de-activated but reception is still possible. This mode  
is accessible by an SPI command and is available in SBC Normal and SBC Stop Mode.  
11.2.4  
LIN Wake Capable Mode  
This mode can be used in SBC Stop, Sleep, Restart and Normal Mode by programming via SPI and it is used to  
monitor bus activities. It is automatically accessed in SBC Fail-Safe Mode. A wake up is detected, if a recessive

OPTIREG™ SBC TLE9263-3BQXV33  
LIN Transceiver  
to dominant transition on the LIN bus is followed by a dominant level of longer than tWK,Bus, followed by a  
dominant to recessive transition. The dominant to recessive transition will cause a wake up of the LIN  
transceiver. A wake-up results in a different behavior of the SBC, as described in below Table 25. As a  
signalization to the microcontroller, the RXD_LIN pin is set LOW and will stay LOW until the LIN transceiver is  
changed to any other mode. After a wake-up event the transceiver can be switched to LIN Normal Mode for  
communication.  
Rearming the transceiver for wake capability  
After a BUS wake-up event, the transceiver is woken. However, the LIN1 and LIN2 transceiver mode bits will  
still show wake capable (=‘01’) so that the RXD signal will be pulled low. There are two possibilities how the  
LIN transceiver’s wake capable mode is enabled again after a wake event:  
The LIN transceiver mode must be toggled, i.e. switched to LIN Normal Mode, LIN Receive Only Mode or LIN  
Off, before switching to LIN Wake Capable Mode again.  
Rearming is done automatically when the SBC is changed to SBC Stop, SBC Sleep, or SBC Fail-Safe Mode  
to ensure wake-up capability.  
Wake-Up in SBC Stop and SBC Normal Mode  
In SBC Stop Mode, if a wake-up is detected, it is signaled by the INT output and in the WK_STAT_1 SPI register.  
It is also signaled by RXDLIN put to LOW. The same applies for the SBC Normal Mode. The microcontroller  
should set the device to SBC Normal Mode, there is no automatic transition to Normal Mode.  
For functional safety reasons, the watchdog will be automatically enabled in SBC Stop Mode after a Bus wake  
event in case it was disabled before (if bit WD_EN_ WK_BUS was configured to HIGH before).  
Wake-Up in SBC Sleep Mode  
Wake-up is possible via a LIN message (filter time t > tWK,Bus). The wake-up automatically transfers the SBC into  
the SBC Restart Mode and from there to Normal Mode the corresponding RXD pin in set to LOW. The  
microcontroller is able to detect the low signal on RXD and to read the wake source out of the WK_STAT_1  
register via SPI. No interrupt is generated when coming out of Sleep Mode. The microcontroller can now  
switch the LIN transceiver into LIN Normal Mode via SPI to start communication.

TXD Time-out Feature  
If the TXD signal is dominant for the time t >tTxD_LIN _TO, the TXD time-out function deactivates the LIN  
transmitter output stage temporarily. The transceiver remains in recessive state. The TXD time-out functions  
prevents the LIN bus from being blocked by a permanent LOW signal on the TXD pin, caused by a failure. The  
failure is stored in the SPI flag LIN1_FAIL and LIN2_FAIL. The LIN transmitter stage is activated again after the  
dominant time-out condition is removed. The transceiver configuration stays unchanged.

Bus Dominant Clamping  
If the LIN bus signal is dominant for a time t > tBUS_LIN_TO in LIN Normal and Receive Only Mode, then a bus  
dominant clamping is detected and the SPI bit LIN1_FAIL and LIN2_FAIL is set. The transceiver configuration  
stays unchanged.  
11.2.7  
Undervoltage Detection  
In case the supply voltage is dropping below the VSHS undervoltage detection threshold (VSHS < VSHS,UVD), the  
TLE9263-3BQXV33 disables the output and receiver stages. If the power supply reaches a higher level than the  
undervoltage detection threshold (VSHS > VSHS,UVD), the TLE9263-3BQXV33 continues with normal operation.  
The transceiver configuration stays unchanged.  
11.2.8  
Slope Selection  
The LIN transceiver offers a LIN Low-Slope Mode for 10.4 kBaud communication and a LIN Normal-Slope Mode  
for 20 kBaud communication. The only difference is the behavior of the transmitter. In LIN Low-Slope Mode,  
the  
transmitter uses a lower slew rate to further reduce the EME compared to Normal-Slope Mode. This complies  
with SAE J2602 requirements.By default, the device works in LIN Normal-Slope Mode. The selection of LIN  
Low-Slope Mode is done by an SPI bit LIN_LSM and will become effective as soon as CSN goes ‘HIGH’. Only the  
LIN Slope is changed. The selection is accessible in SBC Normal Mode only.  
11.2.9  
Flash Programming via LIN  
The device allows LIN flash programming, e.g. of another LIN Slave with a communication of up to 115 kBaud.  
This feature is enabled by de-activating the slope control mechanism via a SPI command (bit LIN_FLASH) and  
will become effective as soon as CSN goes ‘HIGH’. The SPI bit can be set in SBC Normal Mode.

Wake and Voltage Monitoring Inputs  
12.2  
Functional Description  
The wake input pins are edge-sensitive inputs with a switching threshold of typically 3V. This means that both  
transitions, HIGH to LOW and LOW to HIGH, result in a signalization by the SBC. The signalization occurs either  
in triggering the interrupt in SBC Normal Mode and SBC Stop Mode or by a wake up of the device in SBC Sleep  
and SBC Fail-Safe Mode.  
Two different wake detection modes can be selected via SPI:  
Static sense: WK inputs are always active  
Cyclic sense: WK inputs are only active for a certain time period (see Chapter 5.2.1)  
Two different filter times of 16µs or 64µs can be selected to avoid a parasitic wake-up due to transients or EMC  
disturbances in static sense configuration.  
The filter time (tFWK1, tFWK2) is triggered by a level change crossing the switching threshold and a wake signal is  
recognized if the input level will not cross again the threshold during the selected filter time.  
Figure 44 shows a typical wake-up timing and parasitic filter.

Figure 44 Wake-up Filter Timing for Static Sense  
The wake-up capability for each WK pin can be enabled or disabled via SPI command in the WK_CTRL_2  
register.  
The wake source for a wake via a WKx pin can always be read in the register WK_STAT_1 at the bits WK1_WU,  
WK2_WU, and WK3_WU.  
The actual voltage level of the WK pin (LOW or HIGH) can always be read in SBC Normal and SBC Stop Mode in  
the register WK_LVL_STAT. During Cyclic Sense, the register show the sampled levels of the respective WK pin.  
If FO2...3 are configured as WK inputs in its alternative function (16µs static filter time), then the wake events  
will be signalled in the register WK_STAT_2.

To ensure a defined and stable voltage levels at the internal comparator input it is possible to configure  
integrated current sources via the SPI register WK_PUPD_CTRL. In addition, the wake detection modes  
(including the filter time) can be configured via the SPI register WK_FLT_CTRL. An example illustration for the  
automatic switching configuration is shown in Figure 45.

be assigned to one or more HS output, which supplies an external circuit connected to the WKx pin, e.g. HS1

Alternate Measurement Function with WK1 and WK2  
12.2.2.1 Block Description  
This function provides the possibility to measure a voltage, e.g. the unbuffered battery voltage, with the  
protected WK1 HV-input. The measured voltage is routed out at WK2. It allows for example a voltage  
compensation for LED lighting by changing the duty cycle of the High-Side outputs. A simple voltage divider  
needs to be placed externally to provide the correct voltage level to the microcontroller A/D converter input.  
The function is available in SBC Normal Mode and it is disabled in all other modes to allow a low-quiescent  
current operation.The measurement function can be used instead of the WK1 and WK2 wake and level  
signalling capability.  
The benefits of the function is that the signal is measured by a HV-input pin and that there is no current flowing  
through the resistor divider during low-power modes.  
The functionality is shown in a simplified application diagram in Figure 65.  
12.2.2.2 Functional Description  
This measurement function is by default disabled. In this case, WK1 and WK2 have the regular wake and  
voltage level signalization functionality. The switch S1 is open for this configuration (see Figure 65).  
The measurement function can be enabled via the SPI bit WK_MEAS.  
If WK_MEAS is set to ‘1’, then the measurement function is enabled and switch S1 is closed in SBC Normal  
Mode. S1 is open in all other SBC modes. If this function the pull-up and down currents of WK1 and WK2 are  
disabled, and the internal WK1 and WK2 signals are gated. In addition, the settings for WK1 and WK2 in the  
registers WK_PUPD_CTRL, WK_FLT_CTRL and WK_CTRL_2 are ignored but changing these setting is not  
prevented. The registers WK_STAT_1 and WK_LVL_STAT are not updated with respect to the inputs WK1 and  
WK2.  
However, if only WK1 or WK2 are set as wake sources and a SBC Sleep Mode command is set, then the SPI_FAIL  
flag will be set and the SBC will be changed into SBC Restart Mode (see Chapter 5.1 also for wake capability  
of WK1 and WK2).

Block and Functional Description

INT

Interrupt logic  
Figure 47 Interrupt Block Diagram  
The interrupt is used to signalize special events in real time to the microcontroller. The interrupt block is  
designed as a push/pull output stage as shown in Figure 47. An interrupt is triggered and the INT pin is pulled  
low (active low) for tINT in SBC Normal and Stop Mode and it is released again once tINT is expired. The minimum  
HIGH-time of INT between two consecutive interrupts is tINTD. An interrupt does not cause a SBC mode change.  
Two different interrupt classes could be selected via the SPI bit INT_ GLOBAL:  
Class 1 (wake interrupt - INT_ GLOBAL=0): all wake-up events stored in the wake status SPI register  
(WK_STAT_1 and WK_STAT_2) cause an interrupt (default setting). An interrupt is only triggered if the  
respective function is also enabled as a wake source (including GPIOx if configured as a wake input). The  
CAN time out signalization CANTO is also considered as a wake source. Therefore, the interrupt mask bit  
CANTO_ MASK has higher priority than the bit INT_ GLOBAL, i.e. Integral is not taken into account for  
CANTO.  
Class 2 (global interrupt - INT_ GLOBAL=1): in addition to the wake-up events, all signalled failures stored  
in the other status registers cause an interrupt (the register WK_LVL_STAT is not generating interrupts)  
Note:  
The errors which will cause SBC Restart or SBC Fail-Safe Mode (Vcc1_UV, WD_FAIL, VCC1_SC, TSD2,  
FAILURE) are the exceptions of an INT generation on status bits. Also POR and DEV_STAT_x and will  
not generate interrupts.  
In addition to this behavior, an INT will be triggered when the SBC is sent to SBC Stop Mode and not all bits  
were cleared in the WK_STAT_1 and WK_STAT_2register.  
The SPI status registers are updated at every falling edge of the INT pulse. All interrupt events are stored in the  
respective register (except the register WK_LVL_STAT) until the register is read and cleared via SPI command.  
A second SPI read after reading out the respective status register is optional but recommended to verify that  
the interrupt event is not present anymore. The interrupt behavior is shown in Figure 48 for class 1 interrupts.  
The behavior for class 2 is identical.  
The INT pin is also used during SBC Init Mode to select the hardware configuration of the device. See  
Chapter 5.1.1 for further information.

Failure Logic  
Figure 49 Simplified Fail Output Block Diagram for FO1/2 and for FO3/TEST  
The fail outputs consist of a failure logic block and three open-drain outputs (FO1, FO2, FO3) with active-low  
signalization.  
The fail outputs are activated due to following failure conditions:  
Watchdog trigger failure (For config 3&4 only after the 2nd watchdog trigger failure and for config 1&2 after  
1st watchdog trigger failure)  
Thermal shutdown TSD2  
VCC1 short to GND  
VCC1 overvoltage (only if the SPI bit VCC1_OV_RST is set)  
After 4 consecutive VCC1 undervoltage event (see Chapter 15.6 for details)  
At the same time SBC Fail-Safe Mode is entered (exceptions are watchdog trigger failures depending on  
selected  
configurations - see Chapter 5.1.1).  
The fail output activation is signalled in the SPI bit FAILURE of the register DEV_STAT.  
For testing purposes only the Fail Outputs can also be activated via SPI by setting the bit FO_ON. This bit is  
independent of the FO failure bits. In case that there is no failure condition, the FO outputs can also be turned  
off again via SPI, i.e. no successful watchdog trigger is needed.  
The entry of SBC Fail-Safe Mode due to a watchdog failure can be configured as described in Chapter 5.1.1.  
In order to deactivate the fail outputs in SBC Normal Mode the failure conditions must not be present anymore  
(e.g. TSD2, VCC1 short circuit, etc) and the bit FAILURE needs to be cleared via SPI command.  
In case of a watchdog failure the correct procedure to deactivate the fail outputs is:  
a successful WD trigger, i.e. WD_FAIL must be cleared  
clearing of the FAILURE bit  
WD_FAIL will also be cleared when going to SBC Sleep or SBC Fail-Safe Mode due to another failure (not a WD  
failure) or if the watchdog is disabled in SBC Stop Mode

Fail Outputs  
Note:  
The Fail output pin is triggered for any of the above described failures. No FAILURE is caused for the  
1st watchdog failure if selected for Config2.  
The three fail outputs are activated simultaneously with following output functionalities:  
FO1: Static fail output  
FO2: 1.25Hz, 50% (typ.) duty cycle, e.g. to generate an indicator signal  
FO3: 100Hz PWM, 20% (typ.) duty cycle, e.g. to generate a dimmed rear light from a break light.  
Note:  
The duty cycle for FO3 can be configured via SPI option to 20%, 10%, 5% or 2.5%. Default value is  
20%. See the register FO_DC for configuration.  
14.1.1  
General Purpose I/O Functionality of FO2 and FO3 as Alternate Function

Figure 50 Simplified General Purpose I/O block diagram for FO2 and FO3/TEST  
The pins are by default configured as FO pins. The configuration is done via the SPI register GPIO_CTRL. The  
alternate function can be:  
Wake Inputs: The detection threshold VGPIOI,th is similar as for the WK inputs. The wake-up detection  
behavior is the same as for WKx pins. Wake events are stored and reported in WK_STAT_2.  
Low-Side Switches: The switch is able to drive currents of up to 10mA (see also VGPIOL,L1). It is self-protected  
with regards to current limitation. No other diagnosis is implemented.  
High-Side Switches: The switch is able to drive currents up to 10mA (see also VGPIOH,H1). It is self-protected  
with regards to current limitation. No other diagnosis is implemented.  
If configured as GPIO then the respective level at the pin will be shown in WK_LVL_STAT in SBC Normal and  
Stop Mode. This is also the case if configured as LS/HS and can serve as a feedback about the respective  
state. GPIO2 is shared with the TEST level bit.

Restart Behavior:  
The behavior during SBC Restart and Fail-Safe Mode as well as the transition to SBC Normal Mode is as follows:  
if configured as Wake Input: it will stay wake capable during SBC Restart Mode and OFF while in SBC Fail-  
Safe Mode. It will resume wake capability when leaving SBC Restart Mode (SPI register is not modified)  
if configured as Low-Side or High-Side: They will be disabled during SBC Restart and Fail-Safe Mode. After  
leaving SBC Restart Mode the previously configured function will be resumed (SPI register is not modified)  
if configured as FO and activated due to a failure: FO will stay activated during SBC Restart Mode and when  
entering SBC Normal Mode (SPI register is not modified)  
Notes  
1. In order to avoid unintentional entry of SBC Development Mode care must be taken that the level of FO3/TEST  
is HIGH during device power up and SBC Init Mode.  
2. The FOx drivers are supplied via VS. However, the GPIO HS switches (FO2, FO3/TEST) are supplied by VSHS

Reset Output Description  
The reset output pin RO provides a reset information to the microcontroller, for example, in the event that the  
output voltage has fallen below the undervoltage threshold VRT1/2/3/4. In case of a reset event, the reset output  
RO is pulled to low after the filter time tRF and stays low as long as the reset event is present plus a reset delay  
time tRD1. When connecting the SBC to battery voltage, the reset signal remains LOW initially. When the output  
voltage Vcc1 has reached the reset default threshold VRT1,r, the reset output RO is released to HIGH after the  
reset delay time tRD1. A reset can also occur due to a watchdog trigger failure. The reset threshold can be  
adjusted via SPI, the default reset threshold is VRT1,f. The RO pin has an integrated pull-up resistor. In case reset  
is triggered, it will be pulled low for Vcc1 1V and for VS VPOR,f (see also Chapter 15.3).  
The timings for the RO triggering regarding VCC1 undervoltage and watchdog trigger is shown in Figure 52.

Soft Reset Description  
In SBC Normal and SBC Stop Mode, it is also possible to trigger a device internal reset via a SPI command in  
order to bring the SBC into a defined state in case of failures. In this case the microcontroller must send a SPI  
command and set the MODE bits to ‘11’ in the M_S_CTRL register. As soon as this command becomes valid,  
the SBC is set back to SBC INIT Mode and all SPI registers are set to their default values (see SPI Chapter 16.5  
and Chapter 16.6).  
Two different soft reset configurations are possible via the SPI bit SOFT_ RESET_RO:  
The reset output (RO) is triggered when the soft reset is executed (default setting, the same reset delay  
time tRD1 applies)  
The reset output (RO) is not triggered when the soft reset is executed  
Note:  
The device must be in SBC Normal Mode or SBC Stop Mode when sending this command.  
Otherwise, the command will be ignored.  
15.2  
Watchdog Function  
The watchdog is used to monitor the software execution of the microcontroller and to trigger a reset if the  
microcontroller stops serving the watchdog due to a lock up in the software.  
Two different types of watchdog functions are implemented and can be selected via the bit WD_WIN:  
Time-Out Watchdog (default value)  
Window Watchdog  
The respective watchdog functions can be selected and programmed in SBC Normal Mode. The configuration  
stays unchanged in SBC Stop Mode.  
Please refer to Table 34 to match the SBC Modes with the respective watchdog modes.

The watchdog timing is programmed via SPI command. As soon as the watchdog is programmed, the timer  
starts with the new setting and the watchdog must be served. The watchdog is triggered by sending a valid  
SPI-write command to the watchdog configuration register. The trigger SPI command is executed when the  
Chip Select input (CSN) becomes HIGH.  
When coming from SBC Init, SBC Restart Mode or in certain cases from SBC Stop Mode, the watchdog timer is  
always started with a long open window. The long open window (tLW = 200ms) allows the microcontroller to  
run its initialization sequences and then to trigger the watchdog via SPI.  
The watchdog timer period can be selected via the watchdog timing bit field (WD_TIMER) and is in the range  
of 10 ms to 1000 ms. This setting is valid for both watchdog types.  
The following watchdog timer periods are available:  
WD Setting 1: 10ms  
WD Setting 2: 20ms  
WD Setting 3: 50ms  
WD Setting 4: 100ms  
WD Setting 5: 200ms  
WD Setting 6: 500ms  
WD Setting 7: 1000ms  
In case of a watchdog reset, SBC Restart or SBC Fail-Safe Mode is entered according to the configuration and  
the SPI bits WD_FAIL are set. Once the RO goes HIGH again the watchdog immediately starts with a long open  
window the SBC enters automatically SBC Normal Mode.  
In SBC Development Mode the watchdog is OFF and therefore no reset and interrupt are generated due to a  
watchdog failure.  
Depending on the configuration, the WD_FAIL bits will be set after a watchdog trigger failure as follows:  
In case an incorrect WD trigger is received (triggering in the closed watchdog window or when the  
watchdog counter expires without a valid trigger) then the WD_FAIL bits will be increased (showing the  
number of incorrect WD triggers)  
For config 2: the bits can have the maximum value of ‘01’  
For config 1, 3 and 4: the bits can have the maximum value of ‘10’  
The WD_FAIL bits are cleared automatically when following conditions apply:

Time-Out Watchdog  
The time-out watchdog is an easier and less secure watchdog than a window watchdog as the watchdog  
trigger can be done at any time within the configured watchdog timer period.  
A correct watchdog service immediately results in starting a new watchdog timer period. Taking the  
tolerances of the internal oscillator into account leads to the safe trigger area as defined in Figure 53.  
If the time-out watchdog period elapses, a watchdog reset is created by setting the reset output RO low and  
the SBC switches to SBC Restart or SBC Fail-Safe Mode.

Window Watchdog  
Compared to the time-out watchdog the characteristic of the window watchdog is that the watchdog timer  
period is divided between an closed and an open window. The watchdog must be triggered within the open  
window.  
A correct watchdog trigger results in starting the window watchdog period by a closed window followed by an  
open window.  
The watchdog timer period is at the same time the typical trigger time and defines the middle of the open  
window. Taking the oscillator tolerances into account leads to a safe trigger area of:  
tWD x 0.72 < safe trigger area < tWD x 1.20.  
The typical closed window is defined to a width of 60% of the selected window watchdog timer period. Taking  
the tolerances of the internal oscillator into account leads to the timings as defined in Figure 54.  
A correct watchdog service immediately results in starting the next closed window.  
Should the trigger signal meet the closed window or should the watchdog timer period elapse, then a  
watchdog reset is created by setting the reset output RO low and the SBC switches to SBC Restart or SBC Fail-  
Safe Mode.

Watchdog Setting Check Sum  
A check sum bit is part of the SPI commend to trigger the watchdog and to set the watchdog setting.  
The sum of the 8 data bits in the register WWD_CTRL needs to have even parity (see Equation (15.1)). This is  
realized by either setting the bit CHECKSUM to 0 or 1. If the check sum is wrong, then the SPI command is  
ignored, i.e. the watchdog is not triggered or the settings are not changed and the bit SPI_FAIL is set.  
The checksum is calculated by taking all 8 data bits into account. The written value of the reserved bit 3 of the  
WWD_CTRL register is considered (even if read as ‘0’ in the SPI output) for checksum calculation, i.e. if a 1 is  
written on the reserved bit position, then a 1 will be used in the checksum calculation.

The watchdog can be disabled for SBC Stop Mode in SBC Normal Mode. For safety reasons, there is a special  
sequence to be followed in order to disable the watchdog as described in Figure 55. Two different SPI bits

The watchdog can be enabled by triggering the watchdog in SBC Stop Mode or by switching back to SBC  
Normal Mode via SPI command. In both cases the watchdog will start with a long open window and the bits  
WD_STM_EN_1 and WD_STM_ EN_0 are cleared. After the long open window the watchdog has to be served  
as configured in the WD_CTRL register.  
Note:  
The bit WD_STM_ EN_0 will be cleared automatically when the sequence is started and it was 1

Watchdog Start in SBC Stop Mode due to Bus Wake  
In SBC Stop Mode the Watchdog can be disabled. In addition a feature is available which will start the  
watchdog with any BUS wake (CAN or LIN) during SBC Stop Mode. The feature is enabled by setting the bit  
WD_EN_ WK_BUS = 1  
(= default value after POR). The bit can only be changed in SBC Normal Mode and needs to be programmed  
before starting the watchdog disable sequence.  
A wake on CAN and LINx will generate an interrupt and the RXD pin for LINx or CAN is pulled to low. By these  
signals the microcontroller is informed that the watchdog is startedwith a long open window. After the long  
open window the watchdog has to be served as configured in the WD_CTRL register.  
To disable the watchdog again, the SBC needs to be switched to Normal Mode and the sequence needs to be  
sent again.

kept LOW and will only be released once VCC1 has crossed VRT1,r and after tRD1 has elapsed.  
In case VS < VPOR,f, an device internal reset will be generated and the SBC is switched OFF and will restart in  
INIT mode at the next VS rising. This is shown in Figure 56.

Undervoltage VS and VSHS  
If the supply voltage VS reaches the undervoltage threshold VS,UV then the SBC does the following measures:  
SPI bit VS_UV is set. No other error bits are set. The bit can be cleared once the condition is not present  
anymore,  
VCC3 is disabled (see Chapter 8.2) unless the control bit VCC3_VS_ UV_OFF is set  
The VCC1 short circuit protection becomes inactive (see Chapter 15.7). However, the thermal protection  
of the device remains active.  
If the undervoltage threshold is exceeded (VS rising) then functions will be automatically enabled again.  
If the supply voltage VSHS passes below the undervoltage threshold (VSHS,UVD) the SBC does the following  
measures:  
HS1...4 are acting accordingly to the SPI setting (see Chapter 9)  
LINx: Transmitter and Receiver are disabled during the VSHS undervoltage condition (see Chapter 11.2.7);  
SPI bit VSHS_UV is set. No other error bits are set. The bit can be cleared once the condition is not present  
anymore,  
VCC1, VCC2, WKx and CAN are not affected by VSHS undervoltage  
15.5  
Overvoltage VSHS  
If the supply voltage VSHS reaches the overvoltage threshold (VSHS,OVD) the SBC triggers the following  
measures:  
HS1...4 are acting accordingly to the SPI setting (see Chapter 9)  
SPI bit VSHS_OV is set. No other error bits are set. The bit can be cleared once the condition is not present  
anymore,  
VCC1, VCC2, VCC3, WKx, LIN and CAN are not affected by VS overvoltage

VCC1 Over-/ Undervoltage and Undervoltage Prewarning  
VCC1 Undervoltage and Undervoltage Prewarning  
15.6.1  
A first-level voltage detection threshold is implemented as a prewarning for the microcontroller. The  
prewarning event is signaled with the bit VCC1_ WARN. No other actions are taken.  
As described in Chapter 15.1 and Figure 57, a reset will be triggered (RO pulled ‘low’) when the VCC1 output  
voltage falls below the selected undervoltage threshold (VRTx). The bit VCC1_UV is set and the SBC will enter  
SBC Restart Mode.  
Note:  
The VCC1_ WARN or VCC1_UV bits are not set in Sleep Mode as VCC1 = 0V in this case

Figure 57 VCC1 Undervoltage Timing Diagram  
An additional safety mechanism is implemented to avoid repetitive VCC1 undervoltage resets due to high  
dynamic loads on VCC1:  
A counter is increased for every consecutive VCC1 undervoltage event (regardless on the selected reset  
threshold),  
The counter is active in SBC Init-, Normal-, and Stop Mode,  
For VS < VS,UV the counter will be stopped in SBC Normal Mode (i.e. the VS UV comparator is always enabled  
in SBC Normal Mode),  
A 4th consecutive VCC1 undervoltage event will lead to SBC Fail-Safe Mode entry and to setting the bit  
VCC1_UV _FS  
This counter is cleared:  
when SBC Fail-Safe Mode is entered,  
when the bit VCC1_UV is cleared,  
when a Soft Reset is triggered.  
Note:  
It is recommended to clear the VCC1_UV bit once it was set and detected.  
15.6.2  
VCC1 Overvoltage  
For fail-safe reasons a configurable VCC1 overvoltage detection feature is implemented for SBC Init- and  
Normal Mode.  
In case the VCC1,OV,r threshold is crossed, the SBC triggers following measures depending on the configuration:  
The bit VCC1_ OV is always set;  
If the bit VCC1_OV_RST is set and CFGP = ‘1’, then SBC Restart Mode is entered. The FOx outputs are  
activated. After the reset delay time (tRD1), the SBC Restart Mode is left and SBC Normal Mode is resumed  
even if the VCC1 overvoltage event is still present (see also Figure 58). The VCC1_OV_RST bit is cleared  
automatically;  
If the bit VCC1_OV_RST is set and CFGP = ‘0’, then SBC Fail-Safe Mode is entered and FOx outputs are  
activated.  
Note:  
Before entering SBC Stop Mode the bit VCC1_OV_RST must be set to ‘0’ to avoid unintentional SBC  
Restart or Fail-Safe Mode entry. The status bit VCC1_ OV could be set unintentionally. The reason is

VCC1 Short Circuit and VCC3 Diagnostics  
The short circuit protection feature for VCC1 is implemented as follows (VS needs to be higher than VS,UV):  
If VCC1 is not above the VRTx within tVCC1,SC after device power up or after waking from SBC Sleep Mode then  
the SPI bit VCC1_SC bit is set, VCC1 is turned OFF, the FOx pins are enabled, FAILURE is set and SBC Fail-  
Safe Mode is entered. The SBC can be activated again via wake on CAN, LINx, WKx.  
The same behavior applies, if VCC1 falls below VRTx for longer than tVCC1,SC  
.
VCC3 diagnosis features are implemented as follows:  
Load Sharing: The external PNP is disabled when VS < VS,UV if VCC3_VS_ UV_OFF = 0 or when in SBC Stop  
Mode if VCC3_LS_ STP_ON = ‘0’. All other diagnostic features are disabled because they are provided via  
VCC1.  
Stand-alone configuration: The external PNP is disabled when VS < VS,UV if VCC3_VS_ UV_OFF = 0. The  
overcurrent limitation is signalled via the bit VCC3_OC according to the selected shunt resistor, VCC3  
undervoltage is signalled via the bit VCC3_UV and the regulator is disabled due to VS undervoltage when  
V
S,UV is reached.  
Note:  
Neither VCC1_SC nor VCC3_UV flags are set during power up of VCC1 or turn on of VCC3 respectively.  
15.8  
VCC2 Undervoltage and VCAN Undervoltage  
An undervoltage warning is implemented for VCC2 and VCAN as follows:  
V
CC2 undervoltage Detection: In case VCC2 will drop below the VCC2,UV,f threshold, then the SPI bit VCC2_UV  
is set and can be only cleared via SPI.  
CAN undervoltage Detection: In case the voltage on VCAN will drop below the VCAN_UV threshold, then the SPI  
bit VCAN_UV is set and can be only cleared via SPI.

Note:  
The VCC2_UV flag is not set during turn-on or turn-off of VCC2.

Thermal Protection  
Three independent and different thermal protection features are implemented in the SBC according to the  
system impact:  
Individual thermal shutdown of specific blocks  
Temperature prewarning of main microcontroller supply VCC1  
SBC thermal shutdown due to VCC1 overtemperature  
15.9.1  
Individual Thermal Shutdown  
As a first-level protection measure the output stages VCC2, CAN, LINx, and HSx are independently switched  
OFF if the respective block reaches the temperature threshold TjTSD1. Then the TSD1 bit is set. This bit can only  
be cleared via SPI once the overtemperature is not present anymore. Independent of the SBC Mode the  
thermal shutdown protection is only active if the respective block is ON.  
The respective modules behave as follows:  
VCC2: Is switched to OFF and the control bits VCC2_ON are cleared. The status bit VCC2_OT is set. Once  
the overtemperature condition is not present anymore, then VCC2 has to be configured again by SPI.  
VCC3 as a stand-alone regulator: Is switched to OFF and the control bits VCC3_ON are cleared. The status  
bit VCC3_OT is set. Once the overtemperature condition is not present anymore VCC3 has to be configured  
again by SPI. It is recommended to clear the VCC3_OT bit before enabling the regulator again.  
VCC3 in load sharing configuration: in case of overtemperature at VCC3 the bit VCC3_OT is set and VCC3 is  
switched off. The regulator will be switched on again automatically once the overtemperature event is not  
present anymore. Also in this case it is recommended to clear the VCC3_OT bit right away.  
CAN: The transmitter is disabled and stays in CAN Normal Mode acting like CAN Receive only mode. The  
status bits CAN_FAIL = ‘01’ are set. Once the overtemperature condition is not present anymore, then the  
CAN transmitter is automatically switched on.  
LINx: The transmitter is disabled and stays in LIN Normal Mode acting like LIN Receive only mode. The  
status bits and LIN2_FAIL respectively are set to ‘01’. Once the overtemperature condition is not present  
anymore, then the LIN transmitter is automatically switched on.  
HSx: If one or more HSx switches reach the TSD1 threshold, then all HSx switches are turned OFF and the  
control bits for HSx are cleared (see registers HS_CTRL1 and HS_CTRL2). The status bits HSx_OC_OT are  
set (see register HS_OC_OT_STAT). Once the overtemperature condition is not present anymore, then HSx  
has to be configured again by SPI.  
Note:  
The diagnosis bits are not cleared automatically and have to be cleared via SPI once the  
overtemperature condition is not present anymore.

Temperature Prewarning  
As a next level of thermal protection a temperature prewarning is implemented if the main supply VCC1  
reaches the thermal prewarning temperature threshold TjPW. Then the status bit TPW is set. This bit can only  
be cleared via SPI once the overtemperature is not present anymore. Independent of the SBC Mode the  
thermal prewarning is only active if the VCC1 is ON.  
15.9.3  
SBC Thermal Shutdown  
As a highest level of thermal protection a temperature shutdown of the SBC is implemented if the main supply  
VCC1 reaches the thermal shutdown temperature threshold TjTSD2. Once a TSD2 event is detected SBC Fail-  
Safe Mode is entered for tTSD2 to allow the device to cool down. After this time has expired, the SBC will  
automatically change via SBC Restart Mode to SBC Normal Mode (see also Chapter 5.1.6).  
When a TSD2 event is detected, then the status bit TSD2 is set. This bit can only be cleared via SPI in SBC  
Normal Mode once the overtemperature is not present anymore. Independent of the SBC Mode the thermal  
shutdown is only active if VCC1 is ON.

SPI Block Description  
The 16-bit wide Control Input Word is read via the data input SDI, which is synchronized with the clock input  
CLK provided by the microcontroller. The output word appears synchronously at the data output SDO (see  
Figure 59).  
The transmission cycle begins when the chip is selected by the input CSN (Chip Select Not), LOW active. After  
the CSN input returns from LOW to HIGH, the word that has been read is interpreted according to the content.  
The SDO output switches to tristate status (high impedance) at this point, thereby releasing the SDO bus for  
other use. The state of SDI is shifted into the input register with every falling edge on CLK. The state of SDO is  
shifted out of the output register after every rising edge on CLK. The SPI of the SBC is not daisy chain capable.  
CSN high to low: SDO is enabled. Status information transferred to output shift register

Failure Signalization in the SPI Data Output  
When the microcontroller sends a wrong SPI command to the SBC, the SBC ignores the information. Wrong  
SPI commands are either invalid SBC mode commands or commands which are prohibited by the state  
machine to avoid undesired device or system states (see below). In this case the diagnosis bit ‘SPI_FAIL’ is set  
and the SPI Write command is ignored (mostly no partial interpretation). This bit can be only reset by actively  
clearing it via a SPI command.  
Invalid SPI Commands leading to SPI_FAIL are listed below:  
Illegal state transitions: Going from SBC Stop to SBC Sleep Mode. In this case the SBC enters in addition the  
SBC Restart Mode;  
Trying to go to SBC Stop or SBC Sleep mode from SBC Init Mode. In this case SBC Normal Mode is entered;  
Uneven parity in the data bit of the WD_CTRL register. In this case the watchdog trigger is ignored or the  
new watchdog settings are ignored respectively;  
In SBC Stop Mode: attempting to change any SPI settings, e.g. changing the watchdog configuration, PWM  
settings and HS configuration settings during SBC Stop Mode, etc.;  
the SPI command is ignored in this case;  
only WD trigger, returning to Normal Mode, triggering a SBC Soft Reset, and Read & Clear status registers  
commands are valid SPI commands in SBC Stop Mode;  
When entering SBC Stop Mode and WK_STAT_1 and WK_STAT_2 are not cleared; SPI_FAIL will not be set  
but the INT pin will be triggered;  
Changing from SBC Stop to Normal Mode and changing the other bits of the M_S_CTRL register. The other  
modifications will be ignored;  
SBC Sleep Mode: attempt to go to Sleep Mode when all bits in the BUS_CTRL_1, BUS_CTRL_2 and  
WK_CTRL_2 registers are cleared. In this case the SPI_FAIL bit is set and the SBC enters Restart Mode.  
Even though the Sleep Mode command is not entered in this case, the rest of the command (e.g modifying  
VCC2 or VCC3) is executed and the values stay unchanged during SBC Restart Mode;  
Note: At least one wake source must be activated in order to avoid a deadlock situation in SBC Sleep Mode,  
i.e. the SBC would not be able to wake up anymore.  
If the only wake source is a timer and the timer is OFF then the SBC will wake immediately from Sleep Mode  
and enter Restart Mode;  
No failure handling is done for the attempt to go to SBC STOP Mode when all bits in the registers  
BUS_CTRL_1, BUS_CTRL_2 and WK_CTRL_2 are cleared because the microcontroller can leave this mode  
via SPI;  
If VCC3 load sharing VCC3_LS is enabled and the microcontroller tries to clear the bit, then the rest of the  
command executed but VCC3_LS will remain set;  
Attempt to enter SBC Sleep Mode if WK_MEAS is set to ‘1’ and only WK1_EN or WK2_EN are set as wake  
sources. Also in this case the SPI_FAIL bit is set and the SBC enters Restart Mode;  
Setting a longer or equal on-time than the timer period of the respective timer;  
SDI stuck at HIGH or LOW, e.g. SDI received all ‘0’ or all ‘1’;  
Note:  
There is no SPI fail information for unused addresses.  
Signalization of the ERR Flag (high active) in the SPI Data Output (see Figure 59):  
The ERR flag presents an additional diagnosis possibility for the SPI communication. The ERR flag is being set  
for following conditions:  
in case the number of received SPI clocks is not 0 or 16,  
in case RO is LOW and SPI frames are being sent at the same time.

Note:  
In order to read the SPI ERR flag properly, CLK must be low when CSN is triggered, i.e. the ERR bit is  
not valid if the CLK is high on a falling edge of CSN  
The number of received SPI clocks is not 0 or 16:  
The number of received input clocks is supervised to be 0- or 16 clock cycles and the input word is discarded  
in case of a mismatch (0 clock cycle to enable ERR signalization). The error logic also recognizes if CLK was high  
during CSN edges. Both errors - 0 bit and 16 bit CLK mismatch or CLK high during CSN edges - are flagged in  
the following SPI output by a “HIGH” at the data output (SDO pin, bit ERR) before the first rising edge of the  
clock is received. The complete SPI command is ignored in this case.  
RO is LOW and SPI frames are being sent at the same time:  
The ERR flag will be set when the RO pin is triggered (during SBC Restart) and SPI frames are being sent to the  
SBC at the same time. The behavior of the ERR flag will be signalized at the next SPI command for below  
conditions:  
if the command begins when RO is HIGH and it ends when RO is LOW,  
if a SPI command will be sent while RO is LOW,  
If a SPI command begins when RO is LOW and it ends when RO is HIGH.  
and the SDO output will behave as follows:  
always when RO is LOW then SDO will be HIGH,  
when a SPI command begins with RO is LOW and ends when RO is HIGH, then the SDO should be ignored  
because wrong data will be sent.  
Notes  
1. It is possible to quickly check for the ERR flag without sending any data bits. i.e. only the CSN is pulled low and  
SDO is observed - no SPI Clocks are sent in this case  
2. The ERR flag could also be set after the SBC has entered SBC Fail-Safe Mode because the SPI communication  
is stopped immediately.

SPI Programming  
For the TLE9263-3BQXV33, 7 bits are used or the address selection (BIT6...0). Bit 7 is used to decide between  
Read Only and Read & Clear for the status bits, and between Write and Read Only for configuration bits. For  
the actual configuration and status information, 8 data bits (BIT15...8) are used.  
Writing, clearing and reading is done byte wise. The SPI status bits are not cleared automatically and must be  
cleared by the microcontroller, e.g. if the TSD2 was set due to overtemperature. The configuration bits will be  
partially automatically cleared by the SBC - please refer to the individual registers description for detailed  
information. During SBC Restart Mode the SPI communication is ignored by the SBC, i.e. it is not interpreted.  
There are two types of SPI registers:  
Control registers: Those are the registers to configure the SBC, e.g. SBC mode, watchdog trigger, etc  
Status registers: Those are the registers where the status of the SBC is signalled, e.g. wake events,  
warnings, failures, etc.  
For the status registers, the requested information is given in the same SPI command in DO.  
For the control registers, also the status of the respective byte is shown in the same SPI command. However,  
if the setting is changed this is only shown with the next SPI command (it is only valid after CSN high) of the  
same register.  
The SBC status information from the SPI status registers, is transmitted in a compressed way with each SPI  
response on SDO in the so called Status Information Field register (see also Figure 60). The purpose of this  
register is to quickly signal the information to the microcontroller if there was a change in one of the SPI status  
registers. In this way, the microcontroller does not need to read constantly all the SPI status registers but only  
those registers, which were changed.  
Each bit in the Status Information Field represents a SPI status register (see Table 36). As soon as one bit is set  
in one of the status registers, then the respective bit in the Status Information Field register will be set. The  
register WK_LVL_STAT is not included in the status Information field. This is listed in Table 36.  
For Example if bit 0 in the Status Information Field is set to 1, one or more bits of the register 100 0001  
(SUP_STAT_1) is set to 1. Then this register needs to be read in a second SPI command. The bit in the Status  
Information Field will be set to 0 when all bits in the register 100 0001 are set back to 0.

SPI Bit Mapping  
The following figures show the mapping of the registers and the SPI bits of the respective registers.  
The Control Registers ‘000 0000’ to ‘001 1110’ are Read/Write Register. Depending on bit 7 the bits are only  
read (setting bit 7 to ‘0’) or also written (setting bit 7 to ‘1’). The new setting of the bit after write can be seen  
with a new read / write command.  
The registers ‘100 0000’ to ‘111 1110’ are Status Registers and can be read or read with clearing the bit (if  
possible) depending on bit 7. To clear a Data Byte of one of the Status Registers bit 7 must be set to 1. The  
registers WK_LVL_STAT, and FAM_PROD_STAT, SWK_OSC_CAL_H_STAT, SWK_OSC_CAL_L_STAT,  
SWK_STAT, SWK_ECNT_STAT, SWK_CDR_STAT1, SWK_CDR_STAT2 are an exception as they show the  
actual voltage level at the respective WK pin (LOW/HIGH), or a fixed family/ product ID respectively and can  
thus not be cleared. It is recommended for proper diagnosis to clear respective status bits for wake events or  
failure. However, in general it is possible to enable drivers without clearing the respective failure flags.  
When changing to a different SBC Mode, certain configurations bits will be cleared automatically or modified:  
The SBC Mode bits are updated to the actual status, e.g. when returning to Normal Mode  
When changing to a low-power mode (Stop/Sleep), the diagnosis bits of the switches and transceivers are  
not cleared. FOx will stay activated if it was triggered before.  
When changing to SBC Stop Mode, the CAN and LIN control bits will not be modified.  
When changing to SBC Sleep Mode, the CAN and LIN control bits will be modified if they were not OFF or  
wake capable before.  
HSx, VCC2 and VCC3 will stay on when going to Sleep-/Stop Mode (configuration can only be done in  
Normal Mode). Diagnosis is active (OC, OL, OT). In case of a failure the switch is turned off and no wake-up  
is issued  
The configuration bits for HSx and VCC2 in stand-alone configuration are cleared in SBC Restart Mode. FOx  
will stay activated if it was triggered before. Depending on the respective configuration, CAN/LIN  
transceivers will be either OFF, woken or still wake capable.  
Note:  
The detailed behavior of the respective SPI bits and control functions is described in Chapter 16.5,  
Chapter 16.6.and in the respective module chapter. The bit type be marked as ‘rwh’ in case the SBC  
will modify respective control bits.

SPI Control Registers  
READ/WRITE Operation (see also Chapter 16.3):  
The ‘POR / Soft Reset Value’ defines the register content after POR or SBC Reset.  
The ‘Restart Value’ defines the register content after SBC Restart, where ‘x’ means the bit is unchanged.  
One 16-bit SPI command consist of two bytes:  
- the 7-bit address and one additional bit for the register access mode and  
- following the data byte  
The numbering of following bit definitions refers to the data byte and correspond to the bits D0...D7 and to  
the SPI bits 8...15 (see also figure before).  
There are three different bit types:  
- ‘r’ = READ: read only bits (or reserved bits)  
- ‘rw’ = READ/WRITE: readable and writable bits  
- ‘rwh’ = READ/WRITE/Hardware: readable/writable bits, which can also be modified by the SBC hardware  
Reserved bits are marked as “Reserved” and always read as “0”. The respective bits shall also be  
programmed as “0”.  
Reading a register is done byte wise by setting the SPI bit 7 to “0” (= Read Only).  
Writing to a register is done byte wise by setting the SPI bit 7 to “1”.  
SPI control bits are in general not cleared or changed automatically. This must be done by the  
microcontroller via SPI programming. Exceptions to this behavior are stated at the respective register  
description and the respective bit type is marked with a ‘h’ meaning that the SBC is able to change the  
register content.  
The registers are addressed wordwise.

If the FO_ON bit is set by the software then it will be cleared by the SBC after SBC Restart Mode was entered  
and the FOx outputs will be disabled. See also Chapter 14 for FOx activation and deactivation.  
2. After triggering a SBC Soft Reset the bits VCC3_V_CFG and VCC3_LS are not reset if they were set before, i.e. it  
stays unchanged, which is stated by the ‘y’ in the POR / Soft Reset Value. POR value: 0000 0000 and Soft Reset

Notes  
1. Changes in the bits LIN_FLASH and LIN_LSM will be effective immediately once CSN goes to ‘1’.’  
2. The reset values for the LIN and CAN transceivers are marked with ‘y’ because they will vary depending on the  
cause of change - see below.  
3. see Figure 31 and Figure 38 for detailed state changes of LIN and CAN Transceiver for different SBC modes.  
4. The bit CAN_2 is not modified by the SBC but can only be changed by the user. Therefore, the access type is  
‘rw’ compared to bits CAN_0 and CAN_1.  
5. In case SYSERR = 0 and the CAN transceiver is configured to ‘x11’ while going to SBC Sleep Mode, it will be  
automatically set to wake capable (‘x01’). The SPI bits will be changed to wake capable. If configured to ‘x10’  
and SBC Sleep Mode is entered, then the transceiver is set to wake capable, while it will stay in Receive Only  
Mode when it had been configured to ‘x10’ when going to SBC Stop Mode. If it had been configured to wake  
capable or OFF then the mode will remain unchanged.The Receive Only Mode has to be selected by the user

before entering SBC Stop Mode. Please refer to Chapter 5.4.4 for detailed information on the Selective Wake  
mode changes.  
6. Failure Handling Mechanism: When the device enters Fail-Safe Mode due to a failure (TSD2, WD-Failure,...),  
then the wake registers BUS_CTRL_1, BUS_CTRL_2 and WK_CTRL_2 are reset to following values (=wake  
sources) ‘xxx0 1001’, ‘0000 0001’ and ‘x0x0 0111’ in order to ensure that the device can be woken again.

Notes  
1. The bit I_PEAK_TH can be modified in SBC Init and Normal Mode. In SBC Stop Mode this bit is Read only but  
SPI_FAIL will not be set when trying to modify the bit in SBC STOP Mode and no INT is triggered in case INT_  
GLOBAL is set.  
2. see Figure 31 and Figure 38 for detailed state changes of LIN and CAN Transceiver for different SBC modes  
3. Failure Handling Mechanism: When the device enters Fail-Safe Mode due to a failure (TSD2, WD-Failure,...),  
then the wake registers BUS_CTRL_1, and WK_CTRL_2 are reset to following values (=wake sources) ‘xxx0  
1001’, and ‘x0x0 0111’ in order to ensure that the device can be woken again.

Notes  
1. WK_MEAS is by default configured for standard WK functionality (WK1 and WK2). The bits WK1_EN and  
WK2_EN are ignored in case WK_MEAS is activated. If the bit is set to ‘1’ then the measurement function is  
enabled during Normal Mode & the bits WK1_EN and WK2_EN are ignored. The bits WK1/”_LVL bits need to be  
ignored as well.  
2. The wake sources LINx and CAN are selected in the register BUS_CTRL_1 and BUS_CTRL_2 by setting the  
respective bits to ‘wake capable’  
3. Failure Handling Mechanism: When the device enters Fail-Safe Mode due to a failure (TSD2, WD-Failure,...),  
then the wake registers BUS_CTRL_1, BUS_CTRL_2 and WK_CTRL_2 are reset to following values (=wake  
sources) ‘xxx0 1001’, ‘0000 0001’ and ‘x0x0 0111’ in order to ensure that the device can be woken again.

Notes  
1. A timer must be first assigned and is then automatically activated as soon as the on-time is configured.  
2. If cyclic sense is selected and the HS switches are cleared during SBC Restart Mode, then also the timer  
settings (period and on-time) are cleared to avoid incorrect switch detection.  
3. In case the timer are set as wake sources and cyclic sense is running, then both cyclic sense and cyclic wake  
will be active at the same time.

Description  
SYS_STAT  
7:0  
System Status Control Byte (bit0=LSB; bit7=MSB)  
Dedicated byte for system configuration, access only by  
microcontroller. Cleared after power up and Soft Reset  
Notes  
1. The SYS_STATUS_CTRL register is an exception for the default values, i.e. it will keep its configured value also  
after a Soft Reset.  
2. This byte is intended for storing system configurations of the ECU by the microcontroller and is only accessible  
in SBC Normal Mode. The byte is not accessible by the SBC and is also not cleared after Fail-Safe or SBC  
Restart Mode. It allows the microcontroller to quickly store system configuration without loosing the data.

Notes  
1. TRIM_EN unlocks the oscillation calibration mode. Only the bit combination ‘11’ is the valid unlock. The pin  
TXDCAN is used for oscillator synchronisation (trimming).  
2. The microcontroller needs to validate the SWK configuration and set ‘CFG_VAL’ to ‘1’. The SBC will only enable  
SWK if CFG_VAL’ to ‘1’. The bit will be cleared automatically by the SBC after a wake up or POR or if a SWK  
configuration data is changed by the microcontroller.  
3. CANTO bit will only be updated inside BUS_STAT while CAN_2 is set. Therefore, an interrupt is only signaled  
upon occurrence of CANTO while CAN_2 (SWK is enabled) is set in SBC Normal and Stop Mode.  
4. TRIM_EN also unlocks the writing to the SWK_OPT_CTRL register in order to enable the alternate low-power  
Receiver for Selective wake to optimize the quiescent current consumption. Only the bit combination ‘11’  
unlocks the calibrations / configurations.  
5. In SBC stop-mode, any write command to a CAN or SWK configuration register will lead to CFG_VAL be set to  
‘0’ (SWK becomes invalid).

1. The bit RX_WK_SEL is used to select the respective receiver during Selective Wake operation. To reduce the  
quiescent current during Frame Detect Mode it is recommended to select the Low-Power Receiver, i.e.  
RX_WK_SEL = ‘1’.

Important: If the RX_WK_SEL bit is changed, then it must be ensured that the values of TRIM_OSC [8:12] bits  
remain unchanged to avoid a change of oscillator frequency.  
2. TRIM_OSC[8:12] represent the 32-steps coarse trimming range, which is not monotonous.  
It is not recommended to change these values.

SPI Status Information Registers  
READ/CLEAR Operation (see also Chapter 16.3):  
One 16-bit SPI command consist of two bytes:  
- the 7-bit address and one additional bit for the register access mode and  
- following the data byte  
The numbering of following bit definitions refers to the data byte and correspond to the bits D0...D7 and to  
the SPI bits 8...15 (see also figure).  
There are two different bit types:  
- ‘r’ = READ: read only bits (or reserved bits)  
- ‘rc’ = READ/CLEAR: readable and clearable bits  
Reading a register is done byte wise by setting the SPI bit 7 to “0” (= Read Only)  
Clearing a register is done byte wise by setting the SPI bit 7 to “1”  
SPI status registers are in general not cleared or changed automatically (an exception are the WD_FAIL  
bits). This must be done by the microcontroller via SPI command  
The registers are addressed wordwise.

Notes  
1. The MSB of the POR/Soft Reset value is marked as ‘y’: the default value of the POR bit is set after Power-on  
reset (POR value = 1000 0000). However it will be cleared after a SBC Soft Reset command (Soft Reset value =  
0000 0000).  
2. During Sleep Mode, the bits VCC1_SC,VCC1_OV and VCC1_UV will not be set when VCC1 is off  
3. The VCC1_UV bit is never updated in SBC Restart Mode, in SBC Init Mode it is only updated after RO was  
released for the first time, it is always updated in SBC Normal and Stop Mode, and it is always updated in any  
SBC modes in a VCC1_SC condition (after VCC1_UV = 1 for >4ms).

Notes  
1. The bits DEV_STAT show the status of the device before it went through Restart. Either the device came from  
regular Sleep Mode (‘10’) or a failure (‘01’ - SBC Restart or SBC Fail-Safe Mode: WD fail, TSD2 fail, VCC_UV fail  
or VCC1_OV if bit VCC1_OV_RST is set) occurred. Failure is also an illegal command from SBC Stop to SBC  
Sleep Mode or going to SBC Sleep Mode without activation of any wake source. Coming from SBC Sleep Mode  
(‘10’) will also be shown if there was a trial to enter SBC Sleep Mode without having cleared all wake flags  
before.  
2. The WD_FAIL bits are configured as a counter and are the only status bits, which are cleared automatically  
by the SBC. They are cleared after a successful watchdog trigger and when the watchdog is stopped (also in  
SBC Sleep and Fail-Safe Mode unless it was reached due to a watchdog failure). See also Chapter 14.1.  
3. The SPI_FAIL bit is cleared only by SPI command  
4. In case of Config 2/4 the WD_Fail counter is frozen in case of WD trigger failure until a successful WD trigger.  
5. If CFG = ‘0’ then a 1st watchdog failure will not trigger the FO outputs or the FAILURE bit but only force the SBC  
into SBC Restart Mode.

2.) Bus dominant time out: Bus will become recessive or transceiver is set to wake capable or switched off.  
3.) Supply undervoltage: as soon as the threshold is crossed again, i.e. VSHS > VS_UV for LIN and VCAN >  
VCAN_UV for CAN  
4.)In all cases (also for TSD shutdown): to enable the Bus transmission again, TXD needs to be HIGH for a  
certain time (transmitter enable time).  
2. The VCAN_UV comparator is enabled if the mode bit CAN_1 = ‘1’, i.e. in CAN Normal or CAN Receive Only Mode.

3. CANTO will be set only if CAN2 = 1 (=SWK Mode enabled). It will be set as soon as CANSIL was set and will stay  
set even in CANSIL it is reset. An interrupt is issued in SBC Stop- and SBC Normal Mode as soon as CANTO is set  
and the interrupt is not masked out, i.e. CANTO_MASK must be set to 1.  
4. The SYSERR Flag is set in case of a configuration error and in case of an error counter overflow (n>32).  
It is only updated if SWK is enabled (CAN_2 = ‘1’). See also Chapter 5.4.3.  
5. CANTO is set asynchronously to the INT pulse. In order to prevent undesired clearing of CANTO and thus  
possibly missing this interrupt, the bit will be prevented from clearing (i.e. cannot be cleared) until the next  
falling edge of INT.
